Non-perturbative effects in the W and Z transverse momentum distribution 1


We use the “dispersive method” to investigate non-perturbative effects in the transverse momentum distribution of vector bosons produced in pp̄ collisions. The assumption of a non-perturbative modification to the running coupling at low scales leads to additional contributions in impact parameter space proportional to −b2 log Q and −b2. Our results, which… (More)
