On the definition of fragmentation functions and the violation of sum rules
John Collins, Ted Rogers
We point out a problem with the formulation and derivations of sum rules for quark fragmentation functions that impacts their validity in QCD, but which potentially points toward a…
Kinematics of Current Region Fragmentation in Semi-Inclusive Deeply Inelastic Scattering
M. Boglione, J. Collins, L. Gamberg +3
Different kinematical regimes of semi-inclusive deeply inelastic scattering (SIDIS) processes correspond to different underlying partonic pictures, and it is important to understan…
Relating Transverse Momentum Dependent and Collinear Factorization Theorems in a Generalized Formalism
J. Collins, L. Gamberg, A. Prokudin +3
We construct an improved implementation for combining transverse-momentum-dependent (TMD) factorization and collinear factorization. TMD factorization is suitable for low transvers…
JaxoDraw: A graphical user interface for drawing Feynman diagrams. Version 2.0 release notes
D. Binosi, J. Collins, C. Kaufhold +1
A new version of the Feynman graph plotting tool JaxoDraw is presented. Version 2.0 is a fundamental re-write of most of the JaxoDraw core and some functionalities, in particular i…
