Poincaré-covariant quark model of electroweak light mesons decays

Autor: Andreev Viktor, Haurysh Vadzim

Publikováno v: EPJ Web of Conferences, Vol 204, p 08006 (2019)

The procedure for obtaining the radiative decay constants of pseudoscalar and vector unflavored mesons in point–form of Poincaré-invariant quantum mechanics is presented. In the course of the work the authors determine the remaining parameters fro

High-precision methods for Coulomb, linear confinement and Cornell potentials in momentum space

Autor: Andreev, Viktor

We use special quadrature formulas for singular and hypersingular integral to numerically solve the Schr\"{o}dinger equation in momentum space with the linear confinement potential, Coulomb and Cornell potentials. It is shown that the eigenvalues of

Report

Nonperturbative region of effective strong coupling

Autor: Andreev, Viktor V.

In the framework of Poincar\'{e} covariant quark model the behavior of running coupling constant $\alpha_{s}\left(Q^{2}\right)$ is considered in $Q < 1 \mbox{GeV}$ region. An analysis was carried out for pseudoscalar and vector mesons with lepton dec
