Investigation of properties of nuclear matter at extremely high temperature and/or extremely high baryon densities under laboratory conditions is one of the fundamental lines of research in high-energy physics. Throughout the past decades, such inves

We propose a renormalizable Standard Model extension based on $$\Delta(54)$$ symmetry which successfully accommodates the recent experimental values of the physical observables of the quark sector, including six quark masses, three quark mixing angle

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

New upper limits on the intrinsic-charm contribution to the proton are obtained on the basis of experimental data on the existence of pentaquarks involving a hidden charm. Possible distributions of heavy quarks within the proton are analyzed.
