Parton Distributions in Nuclei: Overview and Prospect
نویسنده
چکیده
We give a brief overview of nuclear parton distributions. First, the EMC effect is discussed together with possible interpretations such as nuclear binding and Q rescaling. Next, we explain shadowing descriptions: vector-meson-dominance-type and partonrecombination models. Nuclear dependence of Q evolution should be interesting in testing whether or not DGLAP equations could be applied to nuclear structure functions. Status of nuclear sea-quark and gluon distributions is discussed. The structure function b1, which will be measured at HERMES and possibly at ELFE, could shed light on a new aspect of high-energy spin physics.

Parton Distributions in Nuclei
We discuss two topics in this talk. One is a brief overview of nuclear parton distributions, and the other is SU(2)-flavor-symmetry breaking in nuclear antiquark distributions. First, we show that nuclear structure functions F 2 (x) could be explained in a Q rescaling model with parton recombination effects. Then, nuclear gluon distributions are discussed in this parton model. We point out othe...
متن کاملStructure functions of the nucleon and nuclei in neutrino reactions
Determination of parton distribution functions in nuclei is important for calculating nuclear corrections in oscillation experiments, from which detailed information should be extracted on neutrino properties. First, nuclear parton distributions are discussed for explaining high-energy nuclear reaction data. Possible nuclear modification is explained for valence-quark and antiquark distribution...
متن کاملStudies of parton distributions at a neutrino factory
The determination of parton distribution functions in the nucleon and nuclei is important for obtaining precise hadron-reaction cross sections, from which any new exotic signature could be found. We show that a future neutrino factory could provide important information on the parton distributions. First, a recent effort concerning the parametrization of nuclear parton distributions is explaine...
متن کاملTheory and Phenomenology of Generalized Parton Distributions : a Brief Overview
Theory and phenomenology of generalized parton distributions: a brief overview. Abstract The generalized parton distributions are non-perturbative objects, which encode information on long distance dynamics in a number of exclusive processes. They are hybrids of conventional parton densities, distribution amplitudes and hadron form factors. We give a brief review of theoretical developments in ...
متن کاملGeneralized parton distributions of nuclei
We review recent theoretical results on generalized parton distributions (GPDs) of nuclei, emphasizing the following three roles of nuclear GPDs: (i) complementarity to free proton GPDs, (ii) the enhancement of traditional nuclear effects such as nuclear binding, EMC effect, nuclear shadowing, and (iii) an access to novel nuclear effects such as medium modifications of bound nucleons.
