70. Universality and universality-breaking effects in factorized e+e- hadroproduction cross sections

Andrea Simonelli (Istituto Nazionale di Fisica Nucleare)

Recent BELLE measurements provide the cross section for single hadron production from e+e- annihilations, differential in the hadron transverse momentum with respect to the thrust axis.
Universality breaking effects due to process-dependent soft factors make it very difficult to relate this cross section to that corresponding to hadron-pair production in e+e- annihilations, where TMD...

21. Using Jets for TMD search

Jet technics have been used and developed for a while at LHC. I will discuss the compatibility of jet definition with the TMD factorization theorem and how they can be used in TMD investigations.

67. Transversal momentum dependence and production of jets in p-p, p-A and A-A

Krzysztof Kutak (IFJ PAN)

I am going to present recent results on the broadening phenomenon in p-p, p-A and A-A collisions. In p-p and p-A the broadening is described in terms of the ITMD factorization, accounting for Sudakov effects and saturation. In A-A it is due to soft multiple collisions of the jet traversing the QGP.
