Spin dependent structure functions with leading-hadron productions
Parton distribution functions in the nucleons have been obtained primarily through lepton-induced deep-inelastic scattering (DIS) experiments. One of the most important unresolved issues in our current knowledge of parton distributions is the role of gluons for describing the nucleon spin. While gluon polarization, ∆G(x), could in principle be deduced from the Q-evolution of the polarized struc...
متن کاملa contrastive study of rhetorical functions of citation in iranian and international elt scopus journals
writing an academic article requires the researchers to provide support for their works by learning how to cite the works of others. various studies regarding the analysis of citation in m.a theses have been done, while little work has been done on comparison of citations among elt scopus journal articles, and so the dearth of research in this area demands for further investigation into citatio...
Generalized parton correlation functions for a spin-1/2 hadron
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 کاملGeneralized 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...
متن کاملOn the Shape of Hadron Structure Functions
The hypothesis that, in the leading twist approximation and to all orders of perturbative QCD, there exists a momentum scale Q$ at which hadrons are pure valence quark (or antiquark) bound states gives good results for nucleon, pion and kaon structure functions. Perturbative QCD tells us how hadron structure functions, e.g., F;N(x,Q2), evolve with Q2 for high enough Q2. But what about their sha...
