Polarized proton-proton elastic scattering at RHIC

Research output: Chapter in Book/Report/Conference proceedingConference contribution


The Relativistic Heavy Ion Collider provides colliding polarized proton beams of 25 to 250 GeV/c momentum. With silicon strip detectors installed in Roman Pots at about 58 m on either side of the interaction point (IP) of the STAR detector, elastic scattering will be studied at a center of mass (cms) energy of 200 GeV and four momentum transfer squared range of 0.003 GeV2/c2 < \t\ < 0.03 GeV2/c2, with 100% acceptance and full φ coverage. Measurements of single and double spin asymmetries will be carried out with special beam optics. An upgrade with additional Roman pots closer to the IP will increase the kinematic range to \t\ < 1.5 GeV2/c2 at √s = 500 GeV. Simulation studies of the detector acceptance for 200 GeV cms energy will be given.
