The observed pattern of fermion masses and mixing is an outstanding puzzle in particle
physics, generally known as the flavor problem. Over the years, guided by precision neutrino …

We propose a type II seesaw model for light Dirac neutrinos to provide an explanation for the
recently reported anomaly in W boson mass by the CDF collaboration with 7σ statistical …

In the present letter, a Dirac neutrino mass model is presented in the view of the new result
on W boson mass of m WCDF− II= 80.4335±0.0094 GeV, recently reported by the CDF-II …

We consider a concise dark matter scenario in the minimal gauged BL extension of the
standard model (SM), where the global BL (baryon number minus lepton number) symmetry …

We consider a dark matter scenario in the context of the minimal extension of the Standard
Model (SM) with a B− L (baryon number minus lepton number) gauge symmetry, where …

If neutrinos are truly Dirac fermions, the smallness of their masses may still be natural if
certain symmetries exist beyond those of the standard model of quarks and leptons. We …

We present a simple U (1) B 3-3 L 2 gauge standard model extension that can easily
account for the anomalies in R (K) and R (K*) reported by LHCb. The model is economical in …

We consider a concise dark matter (DM) scenario in the context of a nonexotic U (1)
extension of the Standard Model (SM), where a new U (1) X gauge symmetry is introduced …

In this paper, we investigate lepton mass spectra, flavor mixing and CP violation with a
modular S 4 symmetry under the assumption that neutrinos are Dirac fermions. We find that …

We describe the many pathways to generate Majorana and Dirac neutrino mass through
generalized dimension-5 operators a la Weinberg. The presence of new scalars beyond the …
