“…Models that embed the SM weak gauge group into a SU (3) are growing in interest since they feature rich phenomenology and are able to answer interesting theoretical questions [52][53][54][55][56][57][58][59][60][61][62][63][64][65][66][67][68][69][70][71]. In particular, we will concentrate our efforts on models based on the SU (3) L ⊗ U (1) N gauge group.…”

Lepton flavor violation induced by dark matter

Guided by gauge principles we discuss a predictive and falsifiable UV complete model where the Dirac fermion that accounts for the cold dark matter abundance in our Universe induces the lepton flavor violation (LFV) decays μ → eγ and μ → eee as well as μ − e conversion. We explore the interplay between direct dark matter detection, relic density, collider probes and lepton flavor violation to conclusively show that one may have a viable dark matter candidate yielding flavor violation signatures that can be probed in the upcoming experiments. In fact, keeping the dark matter mass at the TeV scale, a sizable LFV signal is possible, while reproducing the correct dark matter relic density and meeting limits from direct-detection experiments.

“…Apart from extending the particle content, there are other types of ideas those might have possible explanation of (g − 2) µ anomaly. These ideas mainly includes extra dimensional model [41,42], technicolor models [43], composite models [44][45][46], etc. In this work, we attempt to explain the (g − 2) µ anomaly while also allowing solutions to some of the flavor anomalies by extending the SM particle content.…”

Despite the immense success of the Standard Model (SM), the hunt for physics beyond the Standard Model is growing because of the recently observed flavor and muon (g − 2) anomaly.Extension of the SM gauge group or the particle content of the SM still remain viable solutions to the observed anomalies, such as anomalous magnetic moment of muon, flavor violation, dark matter etc. In this work, we consider a model containing a leptoquark, a vector-like lepton (VLL), and a real scalar singlet. The model accounts for a dark matter candidate through a Z 2 symmetry in addition to predicting the muon (g − 2) in agreement with the experimental measurement. We also show that lepton flavor violation is also satisfied in a wide range of parameter space. The viable parameter space is then used to present the collider signature coming from the pair production of the leptoquark in 2µ + 2b + E T / channel which can be probed at the 14 TeV LHC run.

“…Moreover, they could also address low energy anomalies [30][31][32][33][34][35][36][37] and might feature interesting astrophysical [38][39][40][41][42][43][44][45][46][47][48] and collider phenomenology via the presence of exotic gauge bosons which are popularly used in many different contexts [36,[48][49][50][51][52][53][54][55][56][57][58][59][60][61][62][63][64].

Lower Mass Bound on the W′ Mass via Neutrinoless Double Beta Decay in a 3-3-1 Model

The discovery of neutrino masses has raised the importance of studies in the context of neutrinoless double beta decay (0νββ), which constitutes a landmark for lepton number violation (LNV). The standard interpretation is that the light massive neutrinos, that we observed oscillating in terrestrial experiments, mediate double beta decay. In the minimal 3-3-1 model (3-3-1M), object of our study, there is an additional contribution that stems from the mixing between a new charged vector boson, W , and the Standard Model W boson. Even after setting this mixing to be very small, we show that tight constraints arise from the non-observation of (0νββ). Indeed, we derive bounds on the mass of the W gauge boson that might exceed those from collider probes, and most importantly push the scale of symmetry breaking beyond its validity, leading to an exclusion bound for the minimal 3-3-1 model.
