Semileptonic decays of vector mesons $$\rho $$ , $$\omega $$ , ϕ into a pion and lepton pair $${{e}^{ + }}{{e}^{ - }},{{\mu }^{ + }}{{\mu }^{ - }}$$ are described in the chiral Nambu–Jona–Lasinio (NJL) model. Mixing of $$\omega $$ with ϕ is tak

In this paper, we present a feasibility study of the first measurement of the longitudinal polarization of a muon from the $$\tau$$ -lepton decay to extract the Michel parameter $$\xi^{\prime}$$ at the future Super Charm-Tau Factory (SCTF). The expec

Investigation of lepton propagation through matter is of importance for cosmic-ray physics and neutrino astronomy. The diffractive scattering of virtual photons is considered as a process that leads to the energy loss of leptons emitting these photon

NOvA is a neutrino experiment deployed at Fermi National Accelerator Laboratory (FNAL, USA) and designed for studying oscillations—namely, the appearance of electron neutrinos and the survival of muon neutrinos. Two detectors, a near and a far one,

We construct a renormalizable B–L standard model (SM) extension with D5 symmetry in which neutrino mass hierarchies and the tiny neutrino masses are generated at leading order by type I seesaw mechanism. The obtained physical parameters are well co

The Super Charm-Tau Factory project proposed at Budker Institute of Nuclear Physics, Siberian Branch, Russian Academy of Sciences, in Novosibirsk is discussed. An electron–positron collider with the luminosity of $$10^{35}$$ cm $${}^{-2}$$ s $${}^{

A flavor model based on $$A_{4}$$ modular group is proposed. We consider the inverse seesaw mechanism to produce the light neutrino masses. Both neutrino and charged lepton masses are obtained in terms of Yukawa coupling ratios and the module $$\tau$

It is shown that, in the framework of four-color symmetry, the restrictions on the masses of scalar leptoquarks are much smaller than those of vector leptoquarks. The processes $${{l}_{i}} \to {{l}_{j}}\gamma $$ with the lepton flavor violation, the

The oscillating probabilities of lepton flavor changing neutrino oscillation processes, where neutrinos are detected by weak charged-current and neutral-current interactions, are calculated in a quantum field-theoretical approach to neutrino oscillat

A simple Standard Model Extension based on $T_7$ flavor symmetry which accommodates lepton mass and mixing with non-zero $\theta_{13}$ and CP violation phase is proposed. At the tree- level, the realistic lepton mass and mixing pattern is derived thr
