Transverse momentum broadening from the lattice

Abstract

We present a calculation of the transverse momentum broadening of a high-energy fundamental-representation particle, as calculated nonperturbatively within EQCD using the technique proposed by Caron-Huot and pioneered by Panero, Schäfer, and Rummukainen. Our results are continuum extrapolated and provided at four temperatures: 250 MeV, 500 MeV, 1 GeV, and 100 GeV.

Comments: 20 pages, 6 figures, 7 tables; corrected for a numerical error in the fitting procedure leading to a factor 2 in the results for $C(b_{\perp })$
