Cutting rules in the real time formalisms at finite temperature
In this paper, we review the set of rules specific to the calculation of the imaginary part of a Green’s function at finite temperature in the real-time formalisms. Emphasis is put on the clarification of a recent controversy concerning these rules in the “1/2” formalism, more precisely on the issue related to the interpretation of these rules in terms of cut diagrams, like at T = 0. On the sec...
متن کاملQCD sum rules at finite temperature
We derive a thermal QCD sum rule for the correlation function of two vector currents in the rho-meson channel. It takes into account the non-perturbative contributions of the additional , O(3)-invariant operators, which appear due to the breakdown of Lorentz invariance at finite temperature. The mixing of the new operators has a drastic effect on their coefficients. Also our evaluation of the t...

متن کاملPions at Finite Temperature from QCD Sum Rules
The temperature corrections to the current algebra Gell-Mann, Oakes, and Renner (GMOR) relation in SU(2)⊗SU(2) are investigated in the framework of QCD sum rules. There are no corrections at leading order in the quark masses. At the next to leading order we find corrections of the form mq T 2, which are small except near the critical temperature. As a by-product we obtain the temperature behavi...
متن کاملQuarkonium at Finite Temperature
There was considerable interest in the properties and the fate of heavy quarkonium states at finite temperature since the famous conjecture by Matsui and Satz [1]. It has been argued that color screening in medium will lead to quarkonium dissociation above deconfinement, which in turn can signal quark gluon plasma formation in heavy ion collisions. The basic assumption behind the conjecture by ...
