131. First attempts at a global fit of unpolarized Transverse Momentum Distributions

Alessandro Bacchetta (University of Pavia and INFN Pavia)

2/1/17, 11:00 AM

I will describe recent efforts to extract Transverse Momentum Distributions (TMDs) from measurements in semi-inclusive DIS, Drell-Yan processes, and Z boson production. These efforts can be considered as the first attempt at a global fit of unpolarized TMDs. The results are encouraging, but several open challenges remain to be addressed and more experimental information is needed to improve...

46. Generalized TMDs

Prof. Andreas Metz (Physics Department, Temple University, Philadelphia)

2/1/17, 11:25 AM

We give a brief overview of the field of Generalized TMDs. In particular, we address the question if/how Generalized TMDs could be measured.

80. Mapping the hadronization description in Pythia to the correlation functions of TMD factorization

Dr Markus Diefenthaler (Jefferson Lab)

2/1/17, 11:50 AM

In a collaboration between Jefferson Lab and the Pythia collaboration, we aim to map the non-perturbative description of hadronization in the Pythia Monte Carlo Event Generator (MCEG) to the correlation functions of TMD factorization. In a LDRD project, we investigate the connection between the description of hadronization phenomena in nuclear and high-energy physics, work towards a MCEG for...

48. Pion in jet asymmetries at RHIC: test of evolution

Alexei Prokudin (Penn State Berks)

2/1/17, 12:15 PM

Recent measurements of spin asymmetry for pion in jet by STAR Collaboration show little sensitivity to QCD evolution. In this talk I will apply TMD factorization to this process and give a detailed explanation of observed asymmetries.
