Strong Couplings Of Radially Excited State Of Heavy Mesons To A Light Vector Meson

In this paper,we have studied the strong couplings of radially excited state of mesons to a light vector meson within the framework of QCD light cone sum rules(LCSR's).So far,the strong couplings between heavy mesons and a light vector meson has been studied in a variety of theoretical frameworks.However,the coupling constants calculated by the light cone sum rules are smaller than other theoretical results.We improved the hadron parts of the light cone sum ruel and rediscussion the strong couplings of BBp and B*Bp in this paper.The radial excited states of B and B*in the hadron parts of the sum rule were isolated,and other high excited states were put into dispersive integration.In addition,we input the ground state coupling constants that Patricia Bll fits,and updated the latest input parameters and light-cone wave function.In the date analysis,we used the fitting method to obtain the coupling constants gB'B? and gB*'B?.
