Description
The equation of state of cold matter in QCD is a central issue in particle physics, nuclear physics as well as the astrophysics of neutron stars. Unfortunately, direct lattice calculation of the equation of state as a function of density using lattice methods are not viable due to an exponentially bad sign problem when a chemical potential is included. However, this need not mean that nothing can be learned about the equation of state of cold matter via lattice studies. This talk explores calculational strategies that evade the sign problem and can provide constraints on the cold matter equation of state via lattice studies of QCD.
