论文摘要
通过使用能量量张量电流的夸克部分，在轻单键总规则方法中计算了$ρ$梅森的重力形式。在被考虑的版本中，能量量张量电流没有保守，因此，似乎有九个formfactor，其中六（三个）对应于能量孔张量电流的守恒（非保存）。我们还将我们的结果与文献中存在的结果进行了比较。
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.
