The glasma initial state at the LHC
  We present results from numerical Classical Yang Mills calculations of the initial stage Glasma field configurations in a relativistic heavy ion collision. We compute the initial gluon multiplicity from RHIC to LHC energies. The initial conditions for the classical field computation are taken from a dipole model parametrization tested on HERA data, meaning that all the parameters, including the normalization and the value of the saturation scale, are fixed from DIS data.
