Towards a spacetime description of hard parton evolution in the quark gluon plasma

Typical energy loss calcuations in AdS/CFT simulations use an initial condition of off-shell pairs of quarks placed back-to-back in the QGP, but a precise and theoretically motivated description of configuration does not exist. Quark virtuality can have noticeable effects on the rate of energy loss so a first principles calculation is needed for the early time behaviour of virtual particles soon after production. We use the Schwinger Keldysh formalism to calculate a perturbative expression for the Energy Momentum Tensor of hard partons created before the formation of the Quark Gluon Plasma. We propose this as a foundational model to use as an initial condition in jet energy loss calculations.
