On High - Energy Inelastic Electron - Proton Scattering

Note on the Impact Parameter Analysis of High Energy Proton Proton Collisions ∗ )

Following a prior analysis of measured pp elastic differential cross sections, the impact parameter representation in terms of profile functions is calculated from two different parametrizations of single diffractive dissociation data. The derivative of this quantity with respect to the collision energy squared s measures the growth rate of the reaction’s blackness. Its distribution in impact p...

Low energy proton-proton scattering in effective field theory

Low energy proton-proton scattering is studied in pionless effective field theory. Employing the dimensional regularization and MS and power divergence subtraction schemes for loop calculation, we calculate the scattering amplitude in S0 channel up to nextto-next-to leading order and fix low-energy constants that appear in the amplitude by effective range parameters. We study regularization sch...

Inelastic Profon - Proton Scattering at Very High Energy

The spin dependence of high energy proton scattering

Motivated by the need for an absolute polarimeter to determine the beam polarization for the forthcoming RHIC spin program, we study the spin dependence of the proton-proton elastic scattering amplitudes at high energy and small momentum transfer. In particular, we examine experimental evidence for the existence of an asymptotic part of the helicity-flip amplitude φ5 which is not negligible rel...
