  1. Correlation betweenPhysics Reach,Luminosity and √s

  2. prerequisites azimuthal asymmetries in DIS ep Physics reach exclusive processes inclusive and semi-inclusive DIS adds their transverse momentum dependence all need √sep > 50 GeV longitudinal motionof spinning quarks and gluons adds their transverse position to access x < 10-3 where sea quarks and gluons dominate • multi-dimensional binning • to reach kT > 1 GeV • to reach |t| > 1 GeV2 experimental program to address these questions: machine & detector requirements
