DESCRIPTION:Speakers: Zhiquan Sun (University of California\, Berkeley)\n\
 nThe renormalization of operators built out of Wilson lines that meet at a
 n angle (cusp) involve what is known as the cusp anomalous dimension\, a u
 niversal object appearing in many processes in QCD due to the divergences 
 from gluonic interactions. In this talk\, I will discuss the vacuum expect
 ation value of a pair of cusped Wilson lines separated in the transverse d
 irection. This configuration can be related to a simple observable in heav
 y quark transverse momentum-dependent (TMD) fragmentation as well as the T
 MD soft function. I will compute the expectation values of cusped Wilson l
 ines in N=4 super Yang-Mills theory at strong coupling via the AdS/CFT cor
 respondence\, an approach complementary to perturbative calculations of th
 e cusp anomalous dimension. I will also discuss the possible generalizatio
 ns of our setup and results to soft functions in other gauge theories with
  a holographic dual.\n\nhttps://indico.slac.stanford.edu/event/10772/
