Motivation a phase transition event-by-event fluctuations statistical (thermal) model ratios of hadron yields hadronic statistical model particle yield fluctuations.

Energy dependence

Centrality dependence STAR

Particle ratio fluctuations ratios of particles volume fluctuations cancel

Particle ratio fluctuations

Statistical model Upper sign for frmions, lower sign for bosons

Model parameters Thermal model codes THERMUS

Volume From Ref. Nucl.Phys.A 772 (2006) 167, in unit of fm3

Energy dependence Data : Full symbols: Model : Open symbols:

Centrality dependence The volume parameter is decided by asking the average number of K- in the model the same as the STAR measured K- integrated rapidity density

Data : Full symbols: Model : Open symbols:

Conclusion Detector acceptance increase of fluctuations at the lower NA49 energies Kinematic cuts & tracking efficiency good description of most central STAR K/ dN/d scaled K/ fluctuations independent of centrality Opposite sign: resonance decay contributions reduced Same sign: other sources of correlations
