Collins-Soper Kernel for TMD Evolution from Lattice QCD

The Collins-Soper kernel relates transverse momentum-dependent parton distribution functions at different energy scales. For small parton transverse momentum qT ∼ ΛQCD, this kernel is non-perturbative and can only be determined with controlled uncertainties through experiment or first-principles calculations. I will describe an exploratory study using quenched lattice QCD to determine the Nf = 0 Collins-Soper kernel at scales in the range 250 MeV < qT < 2 GeV.
