“…For example in a SUSY context, the strong constraints from kaon mixing imply that squarks need to be far above the electroweak scale [25]. A similar situation arises in the simplest SUSY version of the flavor clockwork models [115]. Much stronger suppression of new physics contributions to kaon mixing can be achieved in models with multiple U (1) symmetries, for example in the so-called alignment models [116], or in the models with the non-abelian U (2) flavor symmetries [37][38][39][40].…”

In this white paper for the Snowmass process, we summarize the role flavor model building plays in the quest for new physics. We review approaches to address the non-generic flavor structure of the Standard Model and discuss how new physics models can be made compatible with the stringent constraints from flavor changing processes that indirectly probe very high scales. We also give an overview of the persistent anomalies in B decays and the anomalous magnetic moment of the muon and some of their most popular new physics explanations.

“…LFU tests are usually constructed as ratios (1, 70), or differences (71)(72)(73), of two semileptonic branching ratios, whereby the two concerned branching ratios differ only by the lepton flavor. In particular, since branching ratios are integrals over the phase space of their differential counterparts, the dilepton invariant mass range has to be the same between the two branching ratios concerned.…”

Two topics have recently risen to prominence within the ongoing searches of beyond–Standard Model effects in b and c decays: observables that test lepton flavor universality (LFU) and those that test lepton flavor violation (LFV). A coherent set of measurements suggests nonstandard LFU effects. General arguments relate LFU to LFV, and the observed size of the former gives hope of observable signals for the latter. We attempt a comprehensive discussion of both theoretical and experimental aspects of these tests. The main final message is that all the instruments necessary to fully establish the putative new effects are at hand, thanks to running experiments and their upgrades. Therefore, this subject stands a concrete chance of ushering in genuinely unexpected discoveries.

“…The combinations O 9 − O 10 and O 9 + O 10 correspond to left-handed and right-handed muon currents, respectively. The full set of dimension 6 operators will be considered in [29]. Best fit values for the new physics Wilson coefficients C 9 and C 10 are given for example in [15,16,17,18,19,20].…”

In this white paper for the Snowmass process, we discuss the prospects of probing new physics explanations of the persistent rare B decay anomalies with a muon collider. If the anomalies are indirect signs of heavy new physics, non-standard rates for µ + µ − → bs production should be observed with high significance at a muon collider with center of mass energy of √ s = 10 TeV. The forwardbackward asymmetry of the b-jet provides diagnostics of the chirality structure of the new physics couplings. In the absence of a signal, µ + µ − → bs can indirectly probe new physics scales as large as 86 TeV. Beam polarization would have an important impact on the new physics sensitivity.
