Generalized transverse momentum dependent parton distributions of the nucleon
Parton distributions play an important role in the QCD description of hard scattering processes. In particular, generalized parton distributions (GPDs) and transverse momentum dependent parton distributions (TMDs) have extensively been studied during the last decade. We focus here on the most general form of quark-quark correlation functions, the socalled generalized transverse momentum depende...
متن کاملNon-universality of transverse momentum dependent parton distribution functions
In the field theoretical description of hadronic scattering processes, single transverse-spin asymmetries arise due to gluon initial and final state interactions. These interactions lead to process dependent Wilson lines in the operator definitions of transverse momentum dependent parton distribution functions. In particular for hadron–hadron scattering processes with hadronic final states this...
متن کاملMulti-jet production and transverse momentum dependent parton distributions
We study the impact of transverse-momentum dependent parton distributions on detailed features of multi-jet final states, focusing on angular jet correlations in DIS data. Monte-Carlo simulations of events containing multiple jets are central to a number of processes of interest at LHC energies, see e.g. [1], and further references in [2]. These complex events, characterized by multiple hard sc...
متن کاملGauge Invariance and Renormalization-group Effects in Transverse-momentum Dependent Parton Distribution Functions
A range of issues pertaining to the use of Wilson lines in integrated and transversemomentum dependent (TMD) parton distribution functions (PDF) is discussed. The relation between gauge invariance and the renormalization properties of the Wilson-line integrals is given particular attention. Using an anomalous-dimensions based analysis in the light-cone gauge, a generalized definition of the TMD...
متن کاملT-odd Transverse Momentum Distributions in Quark Models
We present a general formalism for the evaluation of time-reversal odd parton distributions. This formalism is applied to the evaluation of the two T-odd TMDs allowed at the twist-2 level, i.e., the Sivers and the Boer-Mulders functions. We have performed the calculation for two different models of proton structure: a non relativistic constituent quark model and the MIT bag model. The results o...
