Abstract
The correlators of vector and pseudoscalar currents have been calculated in the
external strong magnetic field in SU(2) gluodynamics on the lattice. The masses
of the neutral ρ meson with different spin projections to the
axis parallel to the external magnetic field B were calculated.
The ρ meson mass with zero spin s=0 decreases with the growth of the
magnetic field and the ρ meson masses with increase with the
magnetic field.
