Description
The violent production of a hard, colored object in hadronic collisions causes drastic--but perturbatively calculable--changes to the vacuum. We quantitatively explore this modification of the vacuum produced by strong interactions by explicitly computing the full time and spatial dependence of the QCD energy-momentum tensor associated with a hard production event. The derivation adapts the finite temperature, many-body technology of the Schwinger-Keldysh formalism to scattering problems in perturbative QCD in T = 0 empty space. Applications of our calculation include the creation of a hybrid early-time pQCD/late-time AdS/CFT energy loss model; novel predictions for particle production in high-energy QCD scattering; and new tests of the distribution of matter, energy, and momentum in jets in pp collisions and the redistribution of matter in jets in heavy ion collisions.
