“…Next-generation experiments are likely to either unearth evidence for or concretely rule out this class of scenarios. MeV, even very tiny BSM couplings can have appreciable impacts on the decay branching ratios, making exotic Higgs decays a potent probe of beyond-the-SM interactions [8,13]. This section summarizes the current status and future prospects for Higgs exotic decays that are relevant for the EWPT-motivated h → ss decays.…”

“…Exotic Higgs decays are a cornerstone of the discovery program at both current and future colliders [8][9][10][11][12][13]. At the HL-LHC, detector upgrades, new trigger and analysis strategies, and increased datasets will steadily increase the sensitivity to small branching ratios, especially in subdominant but cleaner final states (notably h → ss → bbτ τ , h → invisible) [14,15].…”

An essential goal of the Higgs physics program at the LHC and beyond is to explore the nature of the Higgs potential and shed light on the mechanism of electroweak symmetry breaking. An important class of models defining the strength and order of the electroweak phase transition is driven by the Higgs boson coupling to a light new state. This Snowmass white paper points out the existence of a region of parameter space where a strongly first order electroweak phase transition is compatible with exotic decays of the SM-like Higgs boson. A dedicated search for exotic Higgs decays can actively explore this framework at the Large Hadron Collider (LHC), while future exotic Higgs decay searches at the highluminosity LHC and future Higgs factories will be vital to conclusively probe the scenario.

“…Because the colliding objects are second-generation fermions themselves, muon colliders have a particular aptitude for testing physics with generation-specific couplings [37][38][39][40][41][42][43][44][45][46][47][48][49]. Finally, high-energy muons have a large probability to radiate collinear gauge bosons in their collisions [3,[50][51][52][53], and can thus act efficiently as "vector boson colliders", with large rates for VBF processes that can be used both to search for new physics [54][55][56][57][58][59][60][61][62] and to make precision measurements of the electroweak sector [63][64][65][66][67][68][69][70][71][72]. That the muons are color-neutral, and produce far fewer hadronic backgrounds, makes them particularly well-suited for this purpose.…”

A muon collider would be a powerful probe of flavor violation in new physics. There is a strong complementary case for collider measurements and precision low-energy probes of lepton flavor violation (as well as CP violation). We illustrate this by studying the collider reach in a supersymmetric scenario with flavor-violating slepton mixing. We find that the collider could discover sleptons and measure the slepton and neutralino masses with high precision, enabling event reconstruction that could cleanly separate flavor-violating new physics signals from Standard Model backgrounds. The discovery reach of a high-energy muon collider would cover a comparably large, and overlapping, range of parameter space to future µ → e conversion and electron EDM experiments, and unlike precision experiments could immediately shed light on the nature of new physics responsible for flavor violation. This complementarity strengthens the case that a muon collider could be an ideal energy-frontier laboratory in the search for physics beyond the Standard Model.

We investigate the interactions of a light scalar with the Higgs boson and second-generation fermions, which trigger new rare decays of the Higgs boson into 4µ, 2µ2γ, 6µ and 4µ2j. We recast current LHC searches to constrain these decays and develop new collider analyses for those channels which are only poorly tested by existing studies. With the currently collected data we can probe branching ratios as small as 1.5 × 10 −5 , 8.7 × 10 −5 , 5.7 × 10 −8 and 1.6 × 10 −7 , respectively. For the High-Luminosity LHC run, considered here to involve 3 ab −1 of integrated luminosity, these numbers go down to 1.3 × 10 −5 , 2.0 × 10 −6 , 3.0 × 10 −9 and 5.4 × 10 −9 , respectively. We also comment on other channels that remain still unexplored.
