ar X iv : h ep - p h / 01 11 17 2 v 2 1 8 N ov 2 00 1 Summary of Working Group 1 : Theory Part

I will summarize theoretical issues in Working Group 1 at Nufact’01. In particular I will clarify a controversy on the optimum baseline L muon energy Eμ for measurements of the CP phase at a neutrino factory. If the uncertainty of the matter effect is assumed to be ±10%, which may be slightly too pessimistic, then the results from two groups agree (L ∼ 1000km, Eμ ∼ 10GeV).

I will summarize theoretical issues in Working Group 1 at Nufact’01. Although there may not be complete agreement yet on the exact optimum baseline L and the muon energy Eμ for measurements of the CP phase at a neutrino factory, all the works done so far indicate that the optimum set (L, Eμ) tends to be smaller than (3000km, 50GeV) if the uncertainty of the matter effect is assumed to be larger...

These lectures give an introduction to thermal perturbation theory, hard thermal loops, and their use in a nonperturbative, approximately self-consistent resummation of the thermodynamical potentials of quantum chromodynamics.
