Title
A parton branching algorithm with transverse-momentum-dependent splitting functions
Author
Abstract
Parton branching methods underlie the Monte Carlo (MC) generators, being therefore of key importance for obtaining high-energy physics predic-tions. We construct a new parton branching algorithm which, for the first time, incorporates the off-shell, transverse-momentum-dependent (TMD) splitting functions, defined from the high-energy limit of partonic decay amplitudes. Based on these TMD splitting functions, we construct a new TMD Sudakov form factor. We present the first MC implementation of the algorithm for the evolution of the TMD and integrated parton distri-bution functions (PDFs). We use this implementation to evaluate small-x corrections to the distributions and verify the momentum sum rule. The presented study is a first step towards a full TMD MC generator covering the small-x phase space.
