Description
By looking for rare (but not exponentially rare) large-angle deflections of a jet or of partons within a jet, experimentalists can find the weakly coupled short-distance quark and gluon quasiparticles (scatterers) within the strongly coupled liquid quark-gluon plasma produced in heavy ion collisions, as was proposed in Ref. [1]. In this previous work, the probability for picking up a given transverse momentum via a Moliere scattering was calculated, but in the limit of infinite parton energy which means zero angle scattering. Here we calculate the Moliere scattering probability for incident partons with finite energy, meaning that we have now calculated the probability for a parton showing up with a nonzero angle with respect to its initial direction due to scattering with the constituents of QGP, using leading order perturbative QCD.
