Electroweak gauge-boson production at small transverse momentum — •Daniel Wilhelm — Johannes Gutenberg-Universität Mainz

Using soft-collinear effective theory (SCET), one can factorize the cross section for electroweak gauge-boson production at hadron colliders and resum large logarithms to all orders. The naive factorization is broken by a collinear anomaly (CA), which leads to infrared safety at vanishing transverse momentum.
