Comparison of pp and anti-pp interactions at the CERN ISR

Thesis/Dissertation ·
OSTI ID:6960590
A comparison of anti-pp and pp interactions is made with data taken using the R608 forward spectrometer at the CERN ISR. The anti-pp elastic scattering differential cross sections are measured, and compared to the pp differential cross sections at ..sqrt..s = 53 GeV, and in the momentum transfer range 0.6 < t< 2.1 GeV/sup 2/ where the pp cross sections exhibit a dip structure. The anti-pp differential cross section at the center of the dip is 1.5sigma above the pp cross section indicating that the dip may not exist in anti-pp scattering. Single particle p/sub 1/ distributions, resonance production, and charged track multiplicities are then compared in the proton fragmentation region of pp and anti-pp interactions. These distributions are identical within the systematic, and statistical uncertainties of the experiment as expected from Charge Conjugation Invariance and Arm-Arm Factorization.
