标题： $B^{\ast}B^{\ast}ρ$ vertex from QCD sum rules

摘要： 形式因子和 $B^{\ast}B^{\ast}\rho$ 顶点的耦合常数是在三点QCD求和规则框架中计算的。 负责形式因子的相关函数在计算时考虑了 $B^{\ast}$ 和 $\rho$ 介子作为非定域态的贡献。 所得的耦合常数数值结果与光锥QCD求和规则计算结果一致。 显示英文摘要

摘要： The form factors and the coupling constants in the $B^{\ast}B^{\ast}\rho$ vertex are evaluated in the framework of three-point QCD sum rules. The correlation functions responsible for the form factors are evaluated considering contributions of both $B^{\ast}$ and $\rho$ mesons as off-shell states. The obtained numerical results for the coupling constants are in agreement with light-cone QCD sum rules calculations.
