The working group on `Physics at High Parton Densities (ep and eA)' plans to explore new opportunities in low x physics at the LHeC with electrons scattering on protons and heavy ions. If you are interested in participating in these studies, please contact the convenors as soon as possible.
Previous studies at HERA, RHIC and the Tevatron have shown gluon and sea quark densities which grow fast as x decreases, leading to questions of unitarisation, parton recombination, the Colour Glass Condensate and other novel strong interaction dynamics. As yet, however, no clear picture has been established. The previously unexplored LHeC low x kinematic region (reaching x ~ 10-6 at Q2 ~ 1 GeV2) could provide a clear understanding of physics at high parton densities in a kinematic region to which perturbative techniques may be applied. Some topics for possible study are listed below. We welcome further suggestions!
