[HTML][HTML] Strong couplings of heavy mesons with kaon meson in three point QCD sum rules
MA Asgarian - Nuclear Physics A, 2021 - Elsevier
The strong interaction between heavy and kaon mesons can consistently described by
coupling constant in an effective lagrangian. Here, the improved strong coupling constants
of g B s 0 B 1 K and g B s 1 B 1 K vertices in the framework of the three-point QCD sum rules
are calculated. The coupling constants are calculated, when both the B 1 and K states are off-
shell. In this calculation, the contributions of the quark-quark, quark-gluon, and gluon-gluon
condensates corrections are considered. By considering the SU f (3) symmetry, the …
