We analyze the transverse momentum broadening in the absence of radiation of an energetic parton propagating through quark-gluon plasma via Soft Collinear Effective Theory (SCET). We show that the probability for picking up transverse momentum k⊥ is given by the Fourier transform of the expectation value of two transversely separated light-like path-ordered Wilson lines. The subtleties about the ordering of operators do not change theˆq value for the strongly coupled plasma of N=4SYM theory. Read More: http://www.worldscientific.com/doi/abs/10.1142/S0218301311019969
