Dissecting the collinear structure of quark splitting at NNLL
Abstract We explore the collinear limit of final-state quark splittings at order α s 2 $$ {\alpha}_s^2 $$ . While at general NLL level, this limit is described simply by a product of leading-order 1 → 2 DGLAP splitting functions, at the NNLL level we need to consider 1 → 3 splitting functions. Here,...
