      Julia Gehrlein (Colorado State University)
      Poster

      The next generation of neutrino oscillation experiments, JUNO, DUNE, and HK, are under construction now and will collect data over the next decade and beyond. As there are no approved plans to follow up this program with more advanced neutrino oscillation experiments, we consider here one option that had gained considerable interest more than a decade ago: a neutrino factory. Such an...

    63. 61. Beam matching for helical FOFO ionization cooling channels
      Rithika Ganesan (University of Tennessee)
      Poster

      Muons produced through pion decay have high emittances, occupying a large volume in phase space. Hence, cooling is required to reduce the muon phase space density before acceleration. Traditional cooling schemes are too slow to be practical for muon beams. A novel technique proposed for muon colliders, ionization cooling, is instead considered. Muons are passed through absorbers, where they...

    64. 35. Benchmarking Direct Detection of Long-Lived Particles at a 10TeV Muon Collider
      Mira Littmann (The University of Chicago)
      Poster

      A future 10TeV muon collider presents exciting opportunities for the direct detection of charged long-lived particles. We present here a study of long-lived staus, using gauge-mediated supersymmetry breaking as a benchmark model. The stau decays into a tau and a gravitino, with the gravitino as a dark matter candidate. Analysis of stau reconstruction efficiency provides insight into the...

      Stefano Tognini (Oak Ridge National Laboratory)
      Poster

      The collider and detector proposed by the International Muon Collider Collaboration (IMCC) will reach a 10 TeV physics frontier as a means to fully understand the Higgs and explore new physics beyond LHC production capabilities. A muon collider has significant advantages, but comes with many challenges. One of such is the detector simulation, and in particular the beam-induced background (BIB)...

    66. 59. Designing a Drift-Channel for Thick-Wedge Final 4D Cooling in a Future 10 TeV Muon Collider
      Ryan Michaud (The University of Chicago)
      Poster

      A future 10 TeV muon collider holds significant promise, enabling precise, percent-level measurements of Standard Model Properties. However, we must first produce, accelerate, and collide muons before they decay. The process begins by accelerating a proton beam and colliding it with a target, producing a “basketball-sized” cloud of muons. In the next step, known as cooling, this muon cloud is...

    67. 71. Development of Beam Instrumentation for a Muon Cooling Demonstrator
      Cici Hanna (Princeton University)
      Poster

      A top priority for muon collider development is the creation of a demonstrator project to establish the feasibility of cooling a muon beam to the required emittance for a collider. The experiments designed for this demonstrator must present evidence of an appropriate reduction in transverse emittance that is robust enough to convince the physics community of the viability of a full collider....

    68. 62. Dijet Thrust Distribution in Soft Collinear Effective Theory for Muon Collisions
      Agustin Romero (Stanford University)
      Poster

      We apply the Soft Collinear Effective Theory for QCD to muon-antimuon collisions that produce two exclusive jets. The hard scattering amplitude for muon-antimuon to q-qbar is matched from full QCD to SCET at Next to Leading Order. We calculate the differential thrust cross section using the matched Wilson coefficients at NLO for the hard function, and the soft functions and jet functions are...

    69. 26. Dual readout in homogenous inorganic scintillators for precision calorimetry
      Grace Cummings (Fermi National Accelerator Laboratory (US))
      Poster

      Homogeneous inorganic scintillator-based calorimeters are the gold standard for electromagnetic energy resolution, but often degrade the hadronic energy resolution achievable at colliders. By incorporating the dual readout technique, we seek to improve the hadronic energy resolution of these calorimeters through the measurement and separation of the scintillation and Cherenkov light in...

    70. 6. Fermion Portal Dark Matter at a Muon Collider
      Pouya Asadi
      Poster

      I will review the reach of a future 10TeV muon collider in the parameter space of fermion portal dark matter models in the freeze-in regime.
      I study different fermion portal models and show that, in the freeze-in regime, their parameter space is bounded from all directions.
      Different fermion portal models give rise to a host of interesting prompt or long-lived particle signals.
      I will show...

    71. 25. Final Cooling Lattice Design with Genetic Algorithms
      Dr Rebecca Taylor (CERN)
      Poster

      Final Cooling is an optimisation problem: Transverse emittance goes down inverse-exponentially, whereas longitudinal emittance increases exponentially.
      The system is simplified to consider only absorber length, initial energy and energy spread, then a genetic algorithm is applied to minimize both emittances.
      Once a solution is chosen, a more advanced lattice design can be constructed.
      A...

      Ruaa Alharthy (University of Wisconsin-Madison)
      Poster

      This study investigates the optimization of pion and muon yields from an 8GeV proton beam incident on a graphite target, as part of a design effort for a muon collider demonstrator. The primary objective is to determine the optimal geometric configuration between the target and a solenoidal capture channel to maximize secondary particle production while mitigating potential damage from...

    73. 4. Initial 6D Cooling in a Charge-Agnostic Design
      Caroline Riggall (University of Tennessee)

      Having an initial cooling stage is essential to reducing the 6D beam emittance early in the channel. Traditional cooling schemes use dipole fields to generate dispersion, selectively passing higher-momentum particles through more absorbing material. The problem with this approach is the charge-specificity of the dispersion function -- necessitating separate channels for $\mu^+$ and $\mu^-$....

    74. 5. Light Axion-Like Particles at Future Lepton Colliders
      Keping Xie (Michigan State University)
      Poster

      Axion-like particles (ALPs) are well-motivated extensions of the Standard Model (SM) that appear in many new physics scenarios, with masses spanning a broad range. In this work, we systematically study the production and detection prospects of light ALPs at future lepton colliders, including electron-positron and multi-TeV muon colliders. At lepton colliders, light ALPs can be produced in...

      Katsuya Yonehara (Fermilab)
      Poster

      The muon collider target must accept extremely intense proton beams and efficiently produce secondary pions. These pions, which span a broad momentum spectrum, must then be captured and transported to a decay channel. In this presentation, I will introduce recent developments in high-power target systems for various accelerator applications and discuss potential design options for muon...

    77. 31. Nonmagnetic Electron Cooling for a Muon Collider
      Dr Delbert Larson (Particle Beam Lasers, Inc.)
      Poster

      Abstract. Skrinsky and Parkhomchuk introduced the concept of ionization cooling in 1981[1] and the muon collider concept was proposed by Neuffer in 1983[2]. Considerable progress has been made on muon collider design, with one baseline design being established by Palmer, et al.[3] in 1995. Present conceptual designs for a muon collider start with a proton beam driver. The protons are directed...

    78. 63. Optimization of Performance Tradeoffs in a Rectilinear 6D Ionization Muon Cooling Channel
      Aubrey Zhang (The University of Chicago)
      Poster

      A major challenge to achieve the requisite beam luminosity for a muon collider is to cool the muon beams generated from targets by up to five orders of magnitude in 6D emittance. Ionization cooling is a promising method that has been proposed in the past. However, given the unavoidable performance tradeoffs in any cooling system, creating a design that effectively meets requirements poses an...

      Jullian Watts (University of Tennessee)
      Poster

      MAIA (Muon Accelerator Instrumented Apparatus) is a detector concept for a 10 TeV muon collider, designed for precision studies of the standard model as well as searches for new physics. Efficient electron reconstruction and identification is essential, as electrons are commonly produced in key processes such as Higgs boson decays. It is difficult to efficiently reconstruct electrons in this...

      Devlin Jenkins (University of Tennessee Knoxville)
      Poster

      Accurate and efficient simulations are necessary for the research and development of particle colliders. A current muon collider design, MAIA, has tungsten nozzles that create a significant amount of initial showering when a particle interacts with them. This is by design in practice, however, it results in a largely unnecessary CPU time during simulation. DDSim tracks each particle...

      Poster

      The study of electroweak gauge boson self-couplings at a muon collider provides a opportunity to probe new physics and deepen our understanding of electroweak symmetry breaking. At multi-TeV, the muon collider effectively acts as a vector boson collider, as vector boson scattering (VBS) becomes the dominant production mechanism due to logarithmic enhancements from gauge boson radiation....

      We present a preliminary lattice based on a bottom up design for a rapidly cycling synchrotron (RCS) accelerator chain for a multi-TeV muon collider based at Fermilab. The RCS rings range in circumference from 6.28 km (that of the Tevatron) to 15.5 km (the current estimate for the maximum that can be accommodated at the Fermilab site). Each ring is either a conventional RCS (consisting of...

      Powerful superconducting (SC) magnets are the workhorses of energy-frontier colliders. The magnetic field strengths required to achieve necessary beam acceleration and cooling at a 10 TeV Muon Collider are projected to reach 20-30T, between 2 to 4 times the strength of the SC electromagnets currently in operation at the Large Hadron Collider (LHC) [1]. In addition to high field strength, these...

    86. 57. Reconstructing Hadronic Tau Decays in the 10 TeV MAIA Detector Concept
      Ethan Martinez (Yale University)
      Poster

      The tau lepton plays a crucial role in probing the Standard Model, offering access to both the Higgs and leptonic sectors of physics. However, reconstructing the tau is inherently challenging due to the fact that it decays before reaching the detector region and must be identified through its decay products. This becomes even more difficult in a muon collider environment, which is subject to...

      Poster

      As one of the main proposed future colliders that will allow us to reach energy scales that can probe Beyond the Standard Model phenomena, muon colliders come with unique challenges. To achieve the desired luminosity, namely 1, 10, and 20 ab-1 for 3, 10, and 14 TeV, respectively, the six-dimensional emittance of the muon beam needs to be reduced significantly in a process described as muon...

      Eliza Howard (The University of Chicago), Tsz Ngong You (The University of Chicago)
      Poster

      With the introduction of beam-induced background from the decay of muons in the beam pipe of future muon colliders, new techniques must be implemented to filter out the large volume of data generated by such events. The potential presence of long-lived novel particles, which evade conventional time-based cuts, motivates the development of geometrical differentiation methods at the on-chip...

      Daniel Abadjiev (The University of Chicago)
      Poster

      At a 10TeV muon collider, a high level of beam induced background (BIB) will overlay signal produced from muon collisions, similar to how pile-up at the HL-LHC will overlay signal from proton-proton collisions. On-detector differentiation of BIB from signal would improve performance of the inner pixel tracker. For the HL-LHC, we are developing a “smartpixel” application specific integrated...
