    Current events

    • RSVP was terminated last month

      • Near- and mid-term future of accelerator- based HEP (BNL and US) does not look bright

      • Performing these compelling Beyond-the-Standard-Model measurements (and others) does not look likely

      • BNL’s significant effort on RSVP now being redirected to other priority research efforts

    • RHIC no longer in immediate jeopardy

      • Budget-driven review of NP facilities: RHIC did well

      • Funds for FY’06 restored by Congress [pre-Katrina]

    Erhic at bnl l.jpg
    eRHIC at BNL

    The compelling questions for eRHIC:

    • What is the nature of confinement and of hadronization in nuclei (compared to nucleons)?

    • What is the structure of the saturated gluon state at low x in hadrons?

    • What is the role of spin in DIS in nucleons and nuclei?

      Need a precision tool to probe these fundamental and universal aspects of QCD: eRHIC

    • Collide High energy & intensity polarized e (or e+) with A, p

    • A new detector for e-p & e-A physics

    Ee = 10 GeV (~5-10 GeV) TO BE BUILT

    Ep = 250 GeV (~50-250 GeV) EXISTS

    EA = 100 GeV/A (~ 10-100 GeV/A) EXISTS
