We review how the muon anomalous magnetic moment (g− 2) and the quest for lepton flavor
violation are intimately correlated. Indeed the decay μ→ e γ is induced by the same …

We explore generalized global symmetries in theories of physics beyond the standard
model. Theories of Z′ bosons generically contain “noninvertible” chiral symmetries, whose …

A bstract In this paper, we explore in detail the cosmological implications of an abelian L μ−
L τ gauge extension of the Standard Model featuring a light and weakly coupled Z′. Such a …

A bstract We present a dark sector model based on gauging the L μ− L τ symmetry that
addresses anomalies in b→ sμ+ μ− decays and that features a particle dark matter …

The extension of Standard Model made by inclusion of additional U (1) gauge L μ-L τ
symmetry can explain the difference between the measured and the predicted value of the …

As experimental null results increase the pressure on heavy weakly interacting massive
particles (WIMPs) as an explanation of thermal dark matter (DM), it seems timely to explore …

We discuss the feasibility of detecting the gauge boson of the U (1) L μ-L τ symmetry, which
possesses a mass in the range between MeV and GeV, at the Belle-II experiment. The …

A bstract In recent years, the gauge group\(\textrm {U}{(1)} _ {L_ {\mu}-{L} _ {\tau}}\) has
received a lot of attention since it can, in principle, account for the observed excess in the …

In the classic type I seesaw mechanism with very heavy right-handed (RH) neutrinos, it is
possible to account for dark matter via RH neutrino portal couplings to a feebly interacting …

It is well known that the differences between the lepton numbers can be gauged with the
standard model matter content. Such extended gauge theories, dubbed as the gauged U (1) …
