Decay constants of heavy vector mesons at finite temperature
Türkan, Arzu; Veliev, Elşen Veli; Azizi, Kazem; Sundu, Hayriye; Kaya, Gülşah (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 ... -
Mesons spectral functions at finite temperature
Veli, Elşen; Azizi, Kazem; Sundu, Hayriye; Kaya, Gülşah; Akşit, Nurcan (IOP Publishing, 2012)We investigate the thermal spectral densities for (pseudo)scalar and vector currents in the framework of the real time formalism when mass of two quarks are different. Such spectral densities are necessary for the ... -
Modifications on nucleon parameters at finite temperature
Azizi, Kazem; Kaya, Gülşah (Springer, 2015-08-25)Taking into account the additional operators coming up at finite temperature, we investigate the mass and residue of the nucleon in the framework of thermal QCD sum rules. We observe that the mass and residue of the nucleon ... -
Thermal behavior of the mass and residue of hyperons
Azizi, Kazem; Kaya, Gülşah (IOP, 2016-05)We investigate the mass and residue of Sigma, Lambda and Xi hyperons at finite temperature in the framework of thermal QCD sum rules. In our calculation, we take into account the additional operators coming up at finite ... -
Thermal modifications of the heavy axial vector mesons properties
Veliev, Elşen Veli; Azizi, Kazem; Sundu, Hayriye; Kaya, Gülşah (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 the heavy axial vector quarkonia
Veliev, Elşen Veli; Azizi, Kazem; Sundu, Hayriye; Kaya, Gülşah (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 ... -
Thermal QCD sum rules study of vector charmonium and bottomonium states
Veliev, Elşen Veli; Azizi, Kazem; Sundu, Hayriye; Kaya, Gülşah; Türkan, Arzu (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 ...
