An advantage of this expression is that it allows for a straightforward calculation of the imaginary part of current correlators, which is the function entering QCDSR. It turns out that there are two distinct thermal contributions, as first pointed out in [3].
Subsequently, the QCDSR will fix the temperature dependence of these parameters together with that of [s.sub.0](T).
This rate can be fully predicted using the QCDSR results for the T-dependence of the parameters entering the vector channel, followed by an extension to finite chemical potential (density).
This topic will be discussed in Section 8 following [78] where a QCDSR analysis at finite [mu] was first proposed.
In fact, the qualitative temperature behaviour of hadronic widths from LQCD agrees with that from QCDSR. This is reassuring given that these two approaches employ very different parameters to describe deconfinement.
The extension of the QCD sum rule programme at T = 0 [2] to finite temperature was first proposed in [3] in the framework of Laplace transform QCDSR [1].
Alternatively, another complete set is the quark-gluon of QCD, as first advocated in [3].This choice allows for a smooth extension of the QCDSR method to finite T.
Finally, QCDSR have been extended to finite T together with finite baryon chemical potential, [[mu].sub.B], [78].
