Gravitational formfactors of the $ρ$ meson in QCD sum rules

By using the quark part of the energy-momentum tensor current, the gravitational formfactors of the $ρ$ meson are calculated within the light-cone sum rules method. In the considered version, the energy-momentum tensor current is not conserved and as a result, there appear nine formfactors, six (three) of which correspond to the conservation (nonconservation) of the energy-momentum tensor current. We also compare our results with the one existing in the literature.
