Studies of structure functions at a low-energy facility
Abstract
Description
We discuss the studies on structure functions at the possible future RCNP facility. At this stage, an electron-proton or proton-proton collider with sqrt{s}=5 - 10 GeV is considered. We explain large-x physics, nuclear modification of sea-quark and gluon distributions, and tensor spin structure function as the interesting topics at the facility. The large-x parton distributions are important for finding new physics beyond QCD in anomalous events such as the CDF jet data. The nuclear parton distributions are valuable in detecting a quark-gluon signature in heavy-ion reactions. The tensor structure function b_1 is a new field of high-energy spin physics. Considering these physics possibilities, we believe that the possible RCNP facility is important for the hadron-structure community.
