DESCRIPTION:Speakers: Olga Solovjeva (NRC "Kurchatov Institute" SSC RF Ins
 titute of Theoretical and Experimental Physics  &amp\; National Research N
 uclear University “MEPhI”)\nWe have explored ground state energies of 
 the light vector mesons on the base of the SU(3) lattice gauge theory. Thi
 s study was performed without dynamical quarks. We have observed the energ
 ies spliting depending on the value of the spin projections on an external
  magnetic field. The ground state energy of neutral mesons with the zero s
 pin projection diminishes with the increase of the field\, while the energ
 y of charged one increases according to the theoretical expectation. The n
 eutral mesons energies with non-zero spin projections increase with the va
 lue of the magnetic field. The Landau level describes the energy of a char
 ged point-like particle in a magnetic field\, while in our calculations we
  took into account the quark structure of a particle and introduced the te
 rm with magnetic polarizability.\nThe background magnetic field enables to
  calculate the magnetic polarizabilities and the magnetic dipole moments o
 f the hadrons. We measured the energy of a meson as a function of the unif
 orm abelian field. In our calculations external magnetic field is constant
  and it's values vary from $0$ up to $2.5 ~GeV^{2}$. The magnetic dipole m
 oment of the charged $\\rho$ meson has been defined for various quark mass
 es more precisely then in our previous work. This value is in good agreeme
 nt with the experimentally obtained value. We have also estimated the magn
 etic dipole moment of the $K^{∗}$ meson.\n\nhttps://indico.particle.meph
