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...

High Energy Electron Proton Scattering in View of Born Approximation

The proton form factor as well the electron proton differential cross section are calculated. The first Born approximation is used to calculate the transition matrix element for the quark system forming the proton target as scattered by the electron. Results are compared with the experiment SLAC-E-136 for elastic electron-proton scattering made in the range of momentum transfer from Q 2 = 2.9 t...
