Gravitational formfactors of the ρ , π , and K mesons in the light-cone QCD sum rules

By using the quark part of the energy-momentum tensor current, the gravitational formfactors of the ρ, π, and K mesons 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, for integer spin J, there appe...
