Abstract
In a tour de force calculation, using new computational techniques, the authors compute the contribution of soft gluons, gluons with momenta smaller than the Debye screening mass, to the pressure of cold nuclear matter, a QCD medium at zero temperature but large chemical potential, at next-to-next-to-next-to-leading order.
