PROTON SCATTERING ON AN ELECTRON GAS

On High - Energy Inelastic Electron - Proton Scattering

Hard Processes in Electron-proton Scattering

This report summarizes some of the recent HERA results obtained by studying hard processes in ep–scattering. By resolving the structure of the proton, hard ep– reactions provide information on the parton content of the proton and may give insight into the dynamics of the exchanged parton cascade. In addition, their study offers the possibility to test the Standard Model, in particular perturbat...

INELASTIC ELECTRON-PROTON AND y-PROTON SCATTERING, ANDTHESTRUCTUREOFTHENUCLEON*

aA model for highly inelastic electron-nucleon scattering at high energies is studied and compared with existing data. This model envisages the proton to be composed of point-like constituents (“partons”) from which the electron scatters incoherently. We propose that the model be tested by observing y-rays scattered inelastically in a similar way from the nucleon. The magnitude of this inelasti...

On radiative corrections for unpolarized electron proton elastic scattering

A statistical analysis of the elastic unpolarized electron proton scattering data shows that, at large momentum transfer, the size and the ǫ dependence of the radiative corrections, as traditionally calculated and applied, may induce large correlations of the parameters of the Rosenbluth fit, which prevent a correct extraction of the electric proton form factor. Using the electron QED structure...

One Theorist’s Perspective on Four Eras of Electron-Proton Scattering

I have to confess: at the time, I had little idea what Sid was talking about. Now I understand that he was planting in the historical record a classical context for the talk I am about to give. As all of you know, Sid was a much more practical man than this quote would suggest. His down-to-earth attitude toward particle theory rubbed off on most of his students. It is exemplified by the followi...
