Generalized parton correlation functions for a spin-0 hadron
The fully unintegrated, off-diagonal quark-quark correlator for a spin-0 hadron is parameterized in terms of so-called generalized parton correlation functions. Such objects are of relevance for the phenomenology of certain hard exclusive reactions. In particular, they can be considered as mother distributions of generalized parton distributions on the one hand and transverse momentum dependent...

Abstract: The fully unintegrated, off-diagonal quark-quark correlator for a spin-1/2 hadron is parameterized in terms of so-called generalized parton correlation functions. Such objects, in particular, can be considered as mother distributions of generalized parton distributions on the one hand and transverse momentum dependent parton distributions on the other. Therefore, our study provides ne...
متن کاملUnraveling hadron structure with generalized parton distributions
The generalized parton distributions, introduced nearly a decade ago, have emerged as a universal tool to describe hadrons in terms of quark and gluonic degrees of freedom. They combine the features of form factors, parton densities and distribution amplitudes—the functions used for a long time in studies of hadronic structure. Generalized parton distributions are analogous to the phase-space W...
متن کاملParton Distribution Functions for the Large Hadron Collider
Precise knowledge of the parton distribution functions (PDFs) of the proton is essential to relate data to theory at the Large Hadron Collider (LHC). I will give an overview of the determination of proton PDFs from global analysis of existing data taken at HERA, the Tevatron and fixedtarget experiments. Recent developments and current status will be described. In particular, a comparison will b...
متن کاملDi-hadron azimuthal correlation and Mach-like cone structure in a parton/hadron transport model
In the framework of a multi-phase transport model (AMPT) with both partonic and hadronic interactions, azimuthal correlations between trigger particles and associated scattering particles have been studied by the mixing-event technique. The momentum ranges of these particles are 3 < p T < 6 GeV/c and 0.15 < p assoc T < 3 GeV/c (soft), or 2.5 < p trig T < 4 GeV/c and 1 < p T < 2.5 GeV/c (hard) i...
