Effective field theories for heavy quarkonium at finite temperature
We discuss the recent development of effective field theories for quarkonium at finite temperature.
متن کاملComplex heavy-quark potential at finite temperature from lattice QCD.
We calculate for the first time the complex potential between a heavy quark and antiquark at finite temperature across the deconfinement transition in lattice QCD. The real and imaginary part of the potential at each separation distance r is obtained from the spectral function of the thermal Wilson loop. We confirm the existence of an imaginary part above the critical temperature T(C), which gr...
متن کاملLattice Calculations of Heavy Quark Potential at Finite Temperature
We report on the lattice calculations of the heavy quark potential at T > 0 in 2+1 flavor QCD at physical quark masses using the Highly Improved Staggered Quark discretization. We study in detail the systematic effects in the determination of the real and imaginary parts of the potential when using the moment method.
متن کاملDecay constants of heavy vector mesons at finite temperature
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 account the traditionally existing operators at T = 0 and also additional operators appearing at finite temperature. Analysis of the obtained thermal sum rules shows that the dec...
متن کاملHeavy Quark Interactions in Finite Temperature QCD
We study the free energy of a heavy quark-antiquark pair in a thermal medium. We constuct a simple ansatz for the free energy for two quark flavors motivated by the Debye-Hückel theory of screening. PACS. 11.15.Ha, 12.38.Mh, 25.75.Nq
