In this study,the strong coupling constants of vertices BBΥ,BB^(∗)Υ,B^(∗)B^(∗)Υ,BB^(∗)ηb,and B^(∗)B^(∗)ηb are analyzed in the framework of QCD sum rules.All possible off-shell cases and the contributions of vacuu...
The strong coupling constants are basic quantities that carry information on the strong interactions among the baryon and meson multiplets as well as information on the nature and internal structures of the involved h...

By studying theηc exclusive decay to double glueballs,we introduce a model to phenomenologically mimic the gluon-pair-vacuum interaction vertices,namely the 0^++model.Based on this model,we study glueball production ...
