Forward & p+A News

The Forward & p+A working group will focus on what physics questions can be addressed by studies at forward rapidity and/or with p(d)+A collisions at RHIC II. By the end of the next RHIC II workshop at BNL (April 29-30), we hope to have identified which measurements can best answer these questions and which are unique to RHIC II. Following that, we are charged with providing a detailed assessment of the accelerator and detector capabilities that will be required to carry through those measurements with sufficient precision to obtain the answers.

Physics Questions

  • Preliminary list of general questions and the measurements needed to address them. This list is preliminary and will be refined by all WG.
  • Initial list of Forward and/or p+A Physics topics.
    • Nuclear effects on small-x partons: shadowing, coherence and saturation, e.g. gluon shadowing from heavy-quark, J/Psi, Psi', Upsilon, hadron production at forward rapdity
    • Energy loss of partons in cold nuclear matter, e.g. for quarks from Drell-Yan
    • Modification of fragmentation functions in cold nuclear matter
    • Flavor asymmetry of the nucleon sea at small-x with Drell-Yan in p+p & p+d collisions
    • Drell-Yan tagged by forward-going baryons

Forward & p+A Topics

  • In order to address the questions above different topics need to be investigated. The feasibility of each proposed measurement as well as its value in understanding the physics will be discussed and evaluated. The following subtopics are linked to "working" pages with (soon) plenty of information.
