Net-baryon number fluctuations in (2+1)-flavor QCD

Understand

We present a lattice study of net-baryon number fluctuations in (2+1)-flavor QCD.

• The results are based on a Taylor expansion of the pressure with respect to the baryon chemical potential.
• We calculate higher moments of the net-baryon number fluctuations and compare with the corresponding resonance gas results.
• We find that for temperature below 0.9T_c the fluctuations seem to agree with the hadron resonance gas predictions.
