Compton-scattering cross section on the proton at high momentum transfer.
Cross-section values for Compton scattering on the proton were measured at 25 kinematic settings over the range s=5-11 and -t=2-7 GeV2 with a statistical accuracy of a few percent. The scaling power for the s dependence of the cross section at fixed center-of-mass angle was found to be 8.0+/-0.2, strongly inconsistent with the prediction of perturbative QCD. The observed cross-section values ar...
متن کاملHigh-momentum Proton Removal from Typeset Using Revt E X 2
The cross section for the removal of high-momentum protons from 16O is calculated for high missing energies. The admixture of high-momentum nucleons in the 16O ground state is obtained by calculating the single-hole spectral function directly in the finite nucleus with the inclusion of short-range and tensor correlations induced by a realistic meson-exchange interaction. The presence of high-mo...
متن کاملProton–Nucleus Cross Section at High Energies
Cross sections for proton inelastic collision with different nuclei are described within the Glauber and multiple scattering approximations. A significant difference between approximate “Glauber” formula and exact calculations with a geometrical scaling assumption for very high-energy cross section is shown. Experimental values of proton–proton cross sections obtained using extensive air shower...
متن کاملAngular Correlations in Proton-proton Collisions Producing a High Transverse Momentum
In an experiment at the CERN ISR, a streamer chamber detector surrounding one of the intersection regions was triggered on large transverse momentum ~r°'s by means of an array of lead-glass counters. The directions of charged particles and "r rays converted in lead-oxide plates inside the streamer chamber were measured. Data were taken at a c.m. energy ofx/s = 53 GeV at two production angles of...
متن کاملBounds in proton-proton elastic scattering at low momentum transfer
We present a bound on the imaginary part of the single helicity-flip amplitude for spin 1/2-spin 1/2 scattering at small momentum transfer. The variational method of Lagrange multipliers is employed to optimize the single-flip amplitude using the values of σtot, σel and diffraction slope as equality constraints in addition to the inequality constraints resulting from unitarity. Such bounds prov...
