Strong coupling constants of bottom and charmed mesons with scalar, pseudoscalar, and axial vector kaons
(American Physical Society, 2011-06-02)
The strong coupling constants, gD(s)DK(0)*, gB(s)BK(0)*, gD(s)*DK, gB(s)*BK, gD(s)*DK1 and gB(s)*BK(1), where K(0)*, K and K(1) are scalar, pseudoscalar, and axial-vector kaon mesons, respectively, are calculated in the ...
Investigation of the B-c -> chi(c2)l((nu)over bar)(-) transition via QCD sum rules
We calculate the transition form factors of the semileptonic in the framework of QCD sum rules taking into account the two-gluon condensate corrections. Using the obtained results of form factors we estimate the decay ...
Semileptonic transition of P-wave bottomonium chi(b0)(1P) to B-c meson
Taking into account the two-gluon condensate contributions, the transition form factors enrolled to the low-energy effective Hamiltonian describing the semileptonic chi(b0) -> B(c)l (nu) over bar, (l = (e, mu, tau)) decay ...
Investigation of the D (s) (*) D-s eta ((')) and B (s) (*) B-s eta ((')) vertices via QCD sum rules
The strong-coupling constants among mesons are very important quantities as they can provide useful information on the nature of strong interaction among hadrons as well as the QCD vacuum. In this article, we investigate ...
Radiative omega(Q)* -> omega(Q)gamma and qi(Q)* -> xi(Q)'gamma transitions in light cone QCD
We calculate the magnetic dipole and electric quadrupole moments associated with the radiative Omega(Q)* -> Omega(Q)gamma and Xi(Q)* -> Xi(Q)'gamma transitions with Q = b or c in the framework of light cone QCD sum rules. ...
