Probing New Physics with at a Muon Collider
We show that bottom-strange production at a high-energy muon collider, , is a sensitive probe of new physics. We consider the full set
of four-fermion contact interactions that contribute to this process at
dimension 6, and discuss the complementarity of a muon collider and of the
study of rare meson decays that also probe said new physics. If a signal
were to be found at a muon collider, the forward-backward asymmetry of the
-jet provides diagnostics about the underlying chirality structure of the
new physics. In the absence of a signal at a center of mass energy of ~TeV,
can indirectly probe new physics at scales close to
~TeV. We also discuss the impact that beam polarization has on the muon
collider sensitivity performance.Comment: 15 Pages, 16 Figure
Snowmass White Paper: Probing New Physics with at a Muon Collider
In this white paper for the Snowmass process, we discuss the prospects of probing new physics explanations of the persistent rare decay anomalies with a muon collider. If the anomalies are indirect signs of heavy new physics, non-standard rates for production should be observed with high significance at a muon collider with center of mass energy of TeV. The forward-backward asymmetry of the -jet provides diagnostics of the chirality structure of the new physics couplings. In the absence of a signal, can indirectly probe new physics scales as large as TeV. Beam polarization would have an important impact on the new physics sensitivity

Left-right SU(4) vector leptoquark model for flavor anomalies
Building on our recent proposal to explain the experimental hints of new
physics in meson decays within the framework of Pati-Salam quark-lepton
unification, through the interactions of the vector leptoquark,
we construct a realistic model of this type based on the gauge group and
consistent with all experimental constraints. The key feature of the model is
that is broken at a high scale, which suppresses right-handed
lepton flavor changing currents at the low scale and evades the stringent
bounds from searches for lepton flavor violation. The mass of the leptoquark
can be as low as without the need to introduce mixing of
quarks or leptons with new vector-like fermions. We provide a comprehensive
list of model-independent bounds from low energy processes on the couplings in
the effective Hamiltonian that arises from generic leptoquark interactions, and
then apply these to the model presented here. We discuss various meson decay
channels that can be used to probe the model and we investigate the prospects
for discovering the new gauge boson at future colliders

Report of the Topical Group on Physics Beyond the Standard Model at Energy Frontier for Snowmass 2021
This is the Snowmass2021 Energy Frontier (EF) Beyond the Standard Model (BSM) report. It combines the EF topical group reports of EF08 (Model-specific explorations), EF09 (More general explorations), and EF10 (Dark Matter at Colliders). The report includes a general introduction to BSM motivations and the comparative prospects for proposed future experiments for a broad range of potential BSM models and signatures, including compositeness, SUSY, leptoquarks, more general new bosons and fermions, long-lived particles, dark matter, charged-lepton flavor violation, and anomaly detection
