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 ...
Mass and meson-current coupling constant of the tensor D-2*(2460)
We calculate the mass and meson-current coupling constant of the D-2*(2460) tensor meson in the framework of QCD sum rules. The obtained result on the mass is compatible with the experimental data.
Light cone QCD sum rules study of the semileptonic heavy Xi(Q) and Xi(Q)' transitions to Xi and Sigma baryons
The semileptonic decays of heavy spin-1/2, Xi(b(c)) and Xi(b(c))' baryons to the light spin-1/2, Xi and S baryons are investigated in the framework of light cone QCD sum rules. In particular, using the most general form ...
Thermal properties of the heavy axial vector quarkonia
(Institute of Atomic Physics, 2014)
Using the additional operators coming up at finite temperature, we calculate the masses and decay constants of the P wave heavy axial-vector chi(b1) and chi(c1) quarkonia in the framework of thermal QCD sum rules. In the ...
Investigation of heavy-heavy pseudoscalar mesons in thermal QCD sum rules
(IOP Publishing, 2012-01)
We investigate the mass and decay constant of the heavy-heavy pseudoscalar, B(c), eta(c) and eta(b) mesons in the framework of finite-temperature QCD sum rules. The annihilation and scattering parts of spectral density are ...
Scalar quarkonia at finite temperature
(American Physical Society, 2010-09-28)
Masses and decay constants of the scalar quarkonia, chi(Q0)(Q = b, c) with quantum numbers I-G (J(PC)) = 0(+)(0(++)), are calculated in the framework of the QCD sum rules approach both in vacuum and finite temperature. The ...
Thermal behaviors of light unflavored tensor mesons in the framework of QCD sum rule
(IOP Publishing, 2014)
In this paper, we investigated the sensitivity of the masses and decay constants of f(2)(1270) and a(2)(1320) tensor mesons to the temperature using OCD sum rule approach. In our calculations, we take into account new ...
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 ...
Strong couplings of negative and positive parity nucleons to the heavy baryons and mesons
(American Physical Society, 2015-07-20)
The strong coupling form factors related to the strong vertices of the positive and negative parity nucleons with the heavy Lambda(b[c])[Sigma b[c]] baryons and heavy B*[D*] vector mesons are calculated using a threepoint ...

(Hindawi Publishing Corporation, 2015)
The thermal properties of f(2)(1270), a(2)(1320), and K-2*(1430) light tensor mesons are investigated in the framework of QCD sum rules at finite temperature. In particular, the masses and decay constants of the light ...
