Query: The Glasma, Photons and the Implications of Anisotropy   We introduce distribution functions for quarks and gluons in the Glasma and
discuss how they satisfy various relationships of statistical physics. We use
these distributions to compute photon production in the early stages of heavy
ion collisions. Photon rates satisfy geometric scaling, that is, the emission
rate per unit area scales as a function of the saturation momenta divided by
the transverse momentum of the photon. Photon distributions from the Glasma are
steeper than those computed in the Thermalized Quark Gluon Plasma (TQGP). Both
the delayed equilibration of the Glasma and a possible anisotropy in the
pressure lead to slower expansion and mean times of photon emission of fixed
energy are increased. This delayed emission might allow for larger photon
elliptic flow.
