The magnetic dipole polarizabilities of the vector $\rho^0$ and $\rho^{\pm}$
mesons in $SU(3)$ pure gauge theory are calculated in the article. Based on
this the authors explore the contribution of the dipole magnetic
polarizabilities to the tensor polarization of the vector mesons in external
abelian magnetic field. The tensor polarization leads to the dilepton asymmetry
observed in non-central heavy ion collisions and can be also estimated in
lattice gauge theory.
