“…Such models require at least two new physics fields, in order to have the large chirality flip possible on the internal line. Examples of models of this type include: muophilic dark matter running in the loop [255][256][257][258][259][260][261][262][263], contributions from ALPs coupling to heavy vectorlike leptons [264], anomalous Z [265,266], singlet scalars [265,266], low energy supersymmetry [267][268][269][270][271][272], extended Higgs sectors [273][274][275][276], radiative models for charged fermion or neutrino masses [166,[277][278][279]. There may also be a relation with B anomalies [280][281][282][283][284][285], while implications for Higgs physics were discussed in [134,[286][287][288][289][290].…”

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.

“…The existence of these two anomalies has been addressed in a variety of scenarios, including models with extra Higgs doublets [21][22][23][24][25][26][27][28][29][30][31][32][33][34][35][36][37][38], models with other scalar extensions [39][40][41][42][43][44][45][46][47][48] and supersymmetric models [49][50][51][52][53]. There are also plenty of studies with other approaches such as leptoquarks, vector-like fermions or extra gauge bosons, among others [54][55][56][57][58][59][60][61][62][63][64][65][66][67][68]…”

We consider a type I or type X two Higgs doublets model with a modified lepton sector. The generalized lepton sector is also flavor conserving but with the new Yukawa couplings completely decoupled from lepton mass proportionality. The model is one loop stable under renormalization group evolution and it allows to reproduce the g − 2 muon anomaly together with the different scenarios one can consider for the electron g − 2 anomaly, related to the Cesium and/or to the Rubidium recoil measurements of the fine structure constant. Thorough parameter space analyses are performed to constrain all the model parameters in the different scenarios, either including or not including the recent CDF measurement of the W boson mass. For light new scalars with masses in the 0.2-1.0 TeV range, the muon anomaly receives dominant one loop contributions; it is for heavy new scalars with masses above 1.2 TeV that two loop Barr-Zee diagrams are needed. The electron g − 2 anomaly, if any, must always be obtained with the two loop contributions. The final allowed regions are quite sensitive to the assumptions about perturbativity of Yukawa couplings, which influence unexpected observables like the allowed scalar mass ranges. On that respect, intermediate scalar masses, highly constrained by direct LHC searches, are allowed provided that the new lepton Yukawa couplings are fully scrutinized, including values up to 250 GeV. In the framework of a complete model, fully numerically analysed, we show the implications of the recent M W measurement.

“…Different dark matter phenomenological implications of the (g − 2) µ observation in the U (1) Lµ−Lτ model were discussed already in the literature in Refs. [4][5][6][7][8][9][10][11][12]. Another important DM related phenomenon that we had explored earlier in another work [13], is regarding the enhancement of the neutrino floor, the standard background to the DM signal events in a dark matter direct detection experiment.…”

In this work, we investigate the impact of recent anomalous (g − 2)µ measurement with ∼ 4σ deviation from the SM, probing its effect on a light GeV scale fermionic dark matter (DM). The (g − 2)µ anomaly can be readily explained in the a beyond the SM (BSM) U (1)L µ−Lτ scenario, where only a portion of hitherto allowed parameter space can explain the anomaly. This constraint impacts the enhancement of the neutrino floor, the neutrino background in the DM direct detection experiments. The GeV scale DM is severely constrained by the (g − 2)µ result as it restricts the Z mass in the range of 20 − 200 MeV. That restriction results in absence of s-channel resonant annihilation of the GeV scale DM, therefore resulting in over abundance of the DM relic. Even if t-channel annihilation aided by large couplings can bring the relic density in the observed range, direct detection cross section shoots up. Super-GeV DM gets almost ruled out where as sub-GeV DM gets severely constrained.
