Parton Distributions in Nuclei
S. Kumano
Abstract
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 F2A(x) could be explained in a Q2 rescaling model with parton recombination effects. Then, nuclear gluon distributions are discussed in this parton model. We point out other interesting distributions for future investigations. Second, u- d distributions in nuclei are discussed in order to shed light on nuclear modification of the u- d distribution. -------------------- * This talk was supported by the Yamada Science Foundation.
