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 ...
Thermal properties of light tensor mesons via QCD sum rules
(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 ...
