We calculate the predictions of the Standard Model of particlephysics for the thermodynamics of hot matter createdin heavy ion experiments, e.g. the Relativistic Heavy Ion Collider(RHIC) at Brookhaven, US, and the Large Hadron Collider (LHC), CERN.We use computer simulations to solve the of strong interactions(Quantum Chromodynamics) and extend previous results to finite baryon density.To simulate at finite baryon density is an unsolved problem, partlybecause of a sign problem. By improving on the existing methods weextend the range of available densities to supply informationfor the phenomenology of the running Beam Energy Scan II program.
