Contribution

It provides updated lattice results on QCD thermodynamics with physical quark masses, including the equation of state and fluctuation measurements at finite density.

Findings

QCD equation of state at zero and non-zero chemical potential

First results on baryon number and strangeness fluctuations

Implications for event-by-event fluctuation measurements at RHIC and FAIR

Abstract

We discuss recent progress made studies of bulk thermodynamics of strongly interacting matter through lattice simulations of QCD with an almost physical light and strange quark mass spectrum. We present results on the QCD equation of state at vanishing and non-vanishing quark chemical potential and show first results on baryon number and strangeness fluctuations, which might be measured in event-by-event fluctuations in low energy runs at RHIC as well as at FAIR.
