Multiple quark scattering analysis of proton-proton scattering
Proton-proton scattering is investigated in a model in which the protons are composed of quarks and the scattering is due to multiple collisions of the quarkso By including spin in the calculation it was hoped that the differential cross section data could be described without resorting to quark …

The contribution of two-photon exchange in elastic lepton-proton scattering
… of the electric-to-magnetic ratio of the proton's elastic form factors, GE/GM, have recently been shown to diverge at high momentum transfer, Q2, based on which of two experimental methods is employed. Reanalysis of all results might be able to bring them into agreement if some previously …

Measuring the lepton sign asymmetry in elastic electron-proton scattering with OLYMPUS
… Germany, on the asymmetry between positron-proton and electron-proton elastic scattering cross sections. A non-zero asymmetry is evidence of hard two-photon exchange, which has been hypothesized to cause the discrepancy in measurements of the proton's electromagnetic form factors. …

Measurement of the Strange Quark Contribution to Proton Structure Through Parity Violating Electron -Proton Scattering
At intermediate Q2 of about 0.23 ( GeV/c)2, a consistent value of is seen compared to previous experiments; together with a measurement that may imply a negative value of GsE . For Q2 above 0.5 (GeV/c) 2 a consistently positive value for the linear combination of the strange form factors is seen.

New techniques in low-Q² elastic electron-proton scattering measurements and the proton radius extraction
The proton charge radius is a fundamental property of the proton, sensitive to its charge distribution. The proton radius puzzle is the discrepancy between the muonic hydrogen spectroscopy measurement of 0.84 fm and the consensus of 0.88 fm from two traditional methods, electron-proton scattering …

A measurement of the two-photon exchange effect in elastic electron-proton scattering with OLYMPUS
Elastic electron-proton scattering has long been the tool of choice for the study of the proton form factors, GE(Q 2 ) and GM(Q2 ), which describe the electric and magnetic distributions of the proton as a function of momentum transfer. Recent experiments, measuring the form factors from …

Forward jet production in neutral current deep inelastic scattering with ZEUS at HERA
… at DESY (Hamburg) <br>deep inelastic electron-proton scattering can be investigated at a centre-of-mass energy of 318 GeV. Forward jets as a certain class of neutral current events are selected to probe different parton evolution models. The measured cross sections depending on Bjoerken-x and …

Neutron-deuteron breakup and quasielastic scattering
Quasielastic scattering and deuteron breakup in the 200 MeV region is studied by impinging a pulsed neutron beam on a deuterium target at the Weapons Neutron Research facility at the Los Alamos Neutron Science Center. The scattered neutrons from the d(n,np)n reaction are detected by a wall of …

Hadron production in high energy muon scattering
We have performed an experiment to study muon-proton scattering at an incident energy of 225 GeV and a total effective flux of 4.3 x 1010 muons. This experiment is able to detect charged particles in coincidence with the scattered muon in the forward hemisphere, and we report results for the …

Test of New Readout Electronics for the BONuS12 Experiment
<p>For decades, electron-proton scattering experiments have been providing a large amount of data on the proton structure function. However, because of the instability of free neutrons, fewer experiments have been able to study the neutron structure function. The BONuS collaboration at Jefferson …
