Temperature Dependence of Gluon and Quark Condensates as from Linear Confinement
A. N. Mitra, W-Y. P. Hwang
The gluon and quark condensates and their temperature dependence are investigated within QCD premises. The input for the former is a gauge invariant kernel made up of the dire…

Isospin Symmetry Breaking in the Quark Condensates, , as Estimated from QCD Sum Rules
W-Y. P. Hwang, Kwei-Chou Yang
Isospin symmetry breaking in the quark condensates, , is a fundamental parameter in both the QCD sum rule studies and the chiral perturbation theory. I…

Nonlocal Condensates in QCD
W-Y. P. Hwang
In the presence of the nontrivial QCD ground state or vacuum, nonlocal condensates are used to characterize the quark or gluon propagator, or other Green functions of higher order.…
