P-p scattering at 90°and hadronic structure of the proton

M. M. Islam, Joe Rosen

Research output: Contribution to journalArticlepeer-review


We explain p-p differential scattering cross section at 90°and laboratory momentum 5-13.4 GeV/c in terms of two optical potentials and distorted-wave Born approximation of the corresponding amplitudes. The radial dependence of these potentials indicates two hadronic density distributions of the proton of root-mean-square radii 0.40 and 0.26 F.
