Quasi-elastic Nuclear Scattering at High Energies
The quasi-elastic scattering of two nuclei is considered in the highenergy optical model. Energy loss and momentum transfer spectra for projectile ions are evaluated in terms of an inelastic multiplescattering series corresponding to multiple knockout of target nucleons. The leading-order correction to the coherent projectile approximation is evaluated. Calculations with uncorrelated wave funct...
متن کاملImpact-Picture Phenomenology for π±p, K±p and pp, p̄p Elastic Scattering at High Energies
We present an extension to πp and Kp elastic scattering at high energies of the impactpicture phenomenology we first proposed more than twenty years ago, for pp and p̄p elastic scattering. We show, in particular, that the analytic form of the opacity function for the proton obtained previously is compatible with the experimental results on πp and Kp elastic scattering at high energies. It is pro...
متن کاملThe diquark and elastic pion-proton scattering at high energies
Small momentum transfer elastic pion-proton cross-section at high energies is calculated assuming the proton is composed of two constituents, a quark and a diquark. We find that it is possible to fit very precisely the data when (i) the pion acts as a single entity (no constituent quark structure) and (ii) the diquark is rather large, comparable to the size of the proton.
متن کاملMultiple scattering theory of proton elastic scattering at intermediate energies.
We derive and calculate the multiple scattering expansion of the Kerman-McManus-Thaler optical potential to second order in the free nucleon-nucleon transition amplitude and clarify the physical content of the interaction. Calculations are presented for the elastic scattering of protons from ' 0 at 135, 200, and 300 MeV incident energies, paying particular attention to the nonlocalities inheren...
متن کاملBhabha Scattering at High Energies
A study of the process, e+e---) e+e-7, where at least one electron scatters at a small angle is presented. Calculations of the process to order o3 and cr4 are reviewed and compared with data from the PEP storage ring. An analysis of data from the Mark II detector shows good agreement with the order cx4 calculation for e7 final states. Preliminary results from the ASP detector agree well with th...
