Fragmentation in Jets: Cone and Threshold Effects
Massimiliano Procura, Wouter J. Waalewijn
We study the fragmentation of (light) quarks and gluons to hadrons inside a jet of cone size R. This allows for a more exclusive analysis of fragmentation than is currently the cas…
Fully-Unintegrated Parton Distribution and Fragmentation Functions at Perturbative k_T
Ambar Jain, Massimiliano Procura, Wouter J. Waalewijn
We define and study the properties of generalized beam functions (BFs) and fragmenting jet functions (FJFs), which are fully-unintegrated parton distribution functions (PDFs) and f…
Fragmentation inside an identified jet
Massimiliano Procura, Iain W. Stewart
Using Soft-Collinear Effective Theory we derive factorization formulae for semi-inclusive processes where a light hadron h fragments from a jet whose invariant mass is measured. Ou…
Parton Fragmentation within an Identified Jet at NNLL
Ambar Jain, Massimiliano Procura, Wouter J. Waalewijn
The fragmentation of a light parton i to a jet containing a light energetic hadron h, where the momentum fraction of this hadron as well as the invariant mass of the jet is measure…
