Simulations on the Event-by-event Fluctuations of the Particle Yield Ratios D. Kresan, V. Friese GSI, Darmstadt, Germany Correlations and Fluctuations in Relativistic Nuclear Collisions Arcetri, Florence July

July D. Kresan Correlations and Fluctuations Workshop, Florence2 Outline Motivation Definition of dynamical fluctuations NA49 results vs. UrQMD – previous studies and consistency UrQMD studies –single particle ratios (K + over pi + /  and vice versa) –acceptance effects –resonance decay influence –hadronic cascades Toy model simulations (K* and  decay)

July D. Kresan Correlations and Fluctuations Workshop, Florence3 Motivation E-b-e fluctuations of the particle yield ratio are proposed as the signature for the critical endpoint But influence of acceptance, resonance decays and hadronic cascades on e-b-e fluctuations remains to be studied Model to start from – UrQMD. Has both resonances and re-scattering

July D. Kresan Correlations and Fluctuations Workshop, Florence4 Dynamical Fluctuations Measure the particle yields ratio in an event : K/  Relative width of distribution :  = RMS / MEAN  data 2 =  fin 2 +  exp 2 +  dyn 2 background Event mixing: no two tracks coming from one real event  mixed  dyn 2 =  data 2   mixed 2

July D. Kresan Correlations and Fluctuations Workshop, Florence6 Acceptance Effects – forward rapidity 44 y > y cm

July D. Kresan Correlations and Fluctuations Workshop, Florence7 Acceptance Effects – momentum cut (PID) 44 y > y cm p lab >3GeV/c Possible reasons for differences: 1.Different UrQMD versions ? 2.Different acceptance conditions (acceptance filter vs. simplified cuts)

July D. Kresan Correlations and Fluctuations Workshop, Florence15 Conclusion Our results of UrQMD simulations are consistent with ones obtained by C.Roland Acceptance has effect on resulting fluctuations K* decay is not the only source of correlations Positive fluctuations of the (K + +K  )/(  + +   ) ratio in UrQMD are mainly due to  decay Possibly charge conservation ??? Interpretation of this observable is feasible ONLY IF yields (and phase space distr.) of all resonances and daughter particles are known
