#### 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 the D (s) (*) D-s eta ((')) and B (s) (*) B-s eta ((')) vertices via QCD sum rules

(Springer, 2013-10-14)

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 ...

#### Thermal properties of D-2* (2460) and D-s2*(2573) tensor mesons using QCD sum rules

(IOP Publishing, 2014-03)

We investigate the masses and decay constants of the heavy-lightD(2)* (2460) and D-s2*(2573) tensor mesons in the framework of thermal QCD sum rules. Taking into account the additional operators arising at finite temperature, ...

#### 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 ...

#### Decay constants of heavy vector mesons at finite temperature

(IOP Publishing, 2012)

This study deals with determination of the decay constants of heavy vector mesons in the framework of the thermal QCD sum rules. We calculate both thermal spectral density and non-perturbative contributions taking into ...

#### Thermal QCD sum rules study of vector charmonium and bottomonium states

(Springer, 2011-09-23)

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 modifications of the heavy axial vector mesons properties

(SISSA, 2012)

We investigate the properties of the heavy axial vector χb1 and χc1 quarkonia at finite temperature. Taking into account the thermal spectral density as well as additional operators coming up at finite temperature and ...

#### 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 ...
