3. Jet axes and universal TMD fragmentation

We study the transverse momentum spectrum of hadrons in jets. By measuring the transverse momentum with respect to a judiciously chosen axis, we find that this observable is insensitive to (the recoil of) soft radiation. For small transverse momenta we show that the effects of the jet boundary factorize, leading to a new transverse-momentum-dependent (TMD) fragmentation function. In contrast...

10. Features of spin dependent transverse momentum distributions: the Helicity and Transversity case

Daniel Gutiérrez Reyes (Complutense University of Madrid)

The factorization theorem for DY and semi-inclusive DIS holds for all leading twist transverse momentum distributions. However a QCD perturbative calculation shows several important characteristics of spin-dependent distributions. We consider the case of Helicity and Transversity, which are the only spin-dependent distributions which can be matched onto integrated twist-2 functions. We...
