The PP2PP Experiment at RHIC
The PP2PP experiment is devoted to the proton-proton elastic scattering measurement at the Relativistic Heavy Ion Collider at the centre-of-mass energies between 50 and 500 GeV and the four-momentum transfer $0.0004 \leq |t| \leq 1.3$ Gev$^2$. The option of polarized proton beams offers a unique possibility to investigate the spin dependence of the proton elastic scattering in a systematic way. The energy dependence of the total and elastic cross section, the ratio of the real to the imaginary part of the forward scattering amplitude, and the nuclear slope parameter will be studied. In the medium $|t|$ region ($|t| \leq 1.3$ Gev$^2$) the energy dependence of the dip structure in the elastic differential cross section will be measured. With polarized beams the measurement of spin dependent observables: the difference of the total cross sections as function of the of initial transverse spin states, the analyzing power and the double spin asymmetries will be used to map the $s$ and $t$ dependence of the proton helicity amplitudes.
