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 ...
gD(s)*DK*(892) and gB(s)*BK*(892) coupling constants in QCD sum rules
(IOP Publishing, 2011-04)
The coupling constants gD*(s) DK*(892) and gB*sBK*(892) are calculated in the framework of three-point QCD sum rules. The correlation functions responsible for these coupling constants are evaluated considering contributions ...
Thermal QCD sum rules study of vector charmonium and bottomonium states
We calculate the masses and leptonic decay constants of the heavy vector quarkonia, J/psi and gamma mesons at finite temperature. In particular, considering the thermal spectral density as well as additional operators ...
B-c Meson at Finite Temperature
In the present work, we investigate properties of B-c meson in the basis of thermal QCD sum rules. The annihilation and scattering parts of spectral density are calculated in the lowest order of perturbation theory. Taking ...
