Harald Appelshäuser, EMMI workshop Münster, Feb. 18-20, 2009 fluctuations Temperature fluctuations are suppressed in the vicinity of the phase boundary if <pt> is measure for T, <pt> fluctuations should also be suppressed Stodolsky, PRL 75 (1995) Shuryak, PLB423 (1998) Stephanov, Rajagopal, Shuryak PRL 81 (1998) BUT: <pt> may not be a good measure for the temperature: Stephanov, Rajagopal, Shuryak PRD 60 (1999): BE-occupation number fluctuations, effects of thermal contact of pions to heat bath, coupling of pions to fluctuating sigma field etc etc etc  <pt>fluctuations should be enhanced, in particular in the vicinity of the CP Harald Appelshäuser, EMMI workshop Münster, Feb. 18-20, 2009

search for pt-fluctuations LQCD: ideal world Heavy-ion collision: finite system size and lifetime, thermalization? can signatures survive subsequent evolution? other sources of „fluctuations“ (correlations): E- and p-conservation resonance decays collective flow quantum statistics mini-jets and their modification etc detector effects need a model which describes all this correctly this model doesnt exist Harald Appelshäuser, EMMI workshop Münster, Feb. 18-20, 2009
