Bc Meson at Finite Temperature
Veliev, Elşen Veli; Azizi, Kazem; Sundu, Hayriye; Akşit, Nurcan (Elsevier, 2011)In the present work, we investigate properties of Bc 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 ... 
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 nonperturbative contributions taking into ... 
Investigation of heavyheavy pseudoscalar mesons in thermal QCD sum rules
Veliev, Elşen Veli; Azizi, Kazem; Sundu, Hayriye; Akşit, Nurcan (IOP Publishing, 201201)We investigate the mass and decay constant of the heavyheavy pseudoscalar, B(c), eta(c) and eta(b) mesons in the framework of finitetemperature QCD sum rules. The annihilation and scattering parts of spectral density are ... 
Investigation of the D (s) (*) Ds eta ((')) and B (s) (*) Bs eta ((')) vertices via QCD sum rules
Yazıcı, Enis; Veliev, Elşen Veli; Azizi, Kazem; Sundu, Hayriye (Springer, 20131014)The strongcoupling 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 ... 
Scalar quarkonia at finite temperature
Veliev, Elşen Veli; Sundu, Hayriye; Azizi, Kazem; Bayar, Melahat (American Physical Society, 20100928)Masses and decay constants of the scalar quarkonia, chi(Q0)(Q = b, c) with quantum numbers IG (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
