QCD 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 کاملΠ-η Mixing from Qcd Sum Rules
The q2 dependence of the π-η mixing amplitude is examined with the use of QCD sum rules. The linear slope of the mixing function θ(q2) is found to be much smaller than that for ρ-ω mixing. Thus the mixing amplitude is approximately the same in the space-like region as in the time-like one, and one may neglect the q2 dependence of the mixing. A comparison between a hadron-meson, an effective chi...
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 کاملFinite energy chiral sum rules in QCD
The saturation of QCD chiral sum rules of the Weinberg-type is analyzed using ALEPH and OPAL experimental data on the difference between vector and axial-vector correlators (V-A). The sum rules exhibit poor saturation up to current energies below the tau-lepton mass. A remarkable improvement is achieved by introducing integral kernels that vanish at the upper limit of integration. The method is...
متن کاملQCD sum rules with finite masses
The concept of QCD sum rules is extended to bound states composed of particles with finite mass such as scalar quarks or strange quarks. It turns out that mass corrections become important in this context. The number of relevant corrections is analyzed in a systematic discussion of the IR-and UV-divergencies, leading in general to a finite number of corrections. The results are demonstrated for...
