Nuclear phenomena and the short distance structure of hadrons. [Review, nuclear correction, quark, gluon, and jet models]

Description: In certain cases, nuclear corrections to hadronic phenomena depend in detail on the nature of quark and gluon interactions, as well as the effects of jet development within the nuclear medium. Applications of quantum chromodynamics to fast particle production in nuclear collisions, nuclear form factors, and shadowing in deep inelastic lepton processes are reviewed. Also discussed is a new approach to particle production in hadron-nucleus, nucleus-nucleus and deep-inelastic nuclear reactions fro… more

eP physics at the CBA

Description: In this report we have tried to demonstrate how a 20 x 400 GeV ep facility at the CBA will complement the physics of high energy e/sup -/e/sup +/ and hadron-hadron colliders. An ep collider will extend tests of the standard model by about an order of magnitude in spacelike momentum transfer, and extend our knowledge of electro-weak processes to a remarkable degree. It will be especially interesting to see if the lefthanded nature of the charged current observed at low spacelike momentum transfe… more

Quark distributions in nuclei: results from lepton probes

Description: Deep inelastic lepton scattering from nuclei indicates that quark-parton distributions are significantly different from the distributions in isolated nucleons. The EMC and SLAC data on iron and deuterium targets show enhanced and suppresed scattering for kinematic regions where Bjorken x < 1. In addition, the SLAC data on /sup 3/He show strong enhancement over results with conventional nuclear theory for x > 1. These data and recent model interpretations are summarized. Detailed comparisons wit… more

Polarization transfer in inelastic scattering and pionic models of the EMC effect

Description: At the 1982 Telluride Conference Magda Ericson spoke about the interest in a measurement of the sigma vector . q vector or spin-longitudinal nuclear response function. It inspired our collaboration to propose a LAMPF experiment, which was subsequently approved, and run in September 1983. In the intervening time the interest has increased dramatically in connection with the European Muon Collaboration (EMC) effect, and the exciting possibility that this ultra high-energy physics result may have … more

Possible Indication of an a-Dependence of R in Deep-Inelastic Electron Scattering From Nuclei

Description: Measurements of R for deuterium, He, Al, Fe and Au were made at Q/sup 2/ = 5 (GeV/c)/sup 2/ and x = 0.3, 0.5 and 0.7. An indication of a possible A-dependence of R has been found which would result in large differences among sigma/sup A//sigma/sup d/, F/sub 2//sup A//F/sub 2//sup d/ and F/sub 1//sup A//F/sub 1//sup d/. 7 references, 4 figures.

Recent Progress in Electron Scattering at SLAC

Description: A new experiment on ep elastic scattering at large momentum transfer, Experiment E136, has recently completed data taking. A new measurement of deep inelastic electron scattering from nuclear targets, Experiment E139, has been completed and preliminary results are available. A new program of experiments has begun, called Nuclear Physics at SLAC (NPAS), that will use a new injector on the SLAC linac to provide high intensity beams in the energy range from 0.5 to 6 GeV.

Measurement of the A-dependence of the EMC effect and R in deep-inelastic electron scattering from nuclei

Description: Significant differences in the inelastic structure functions of Fe, Al, and deuterium nuclei have recently been observed in muon and electron scattering experiments. This has been interpreted as a distortion of the quark momentum distributions in bound nucleons. To study the A-dependence of this effect, we have measured differential cross sections for the inelastic scattering of electrons from deuterium, He, Be, C, Al, Ca, Fe, Ag, and Au over a large kinematic range (x values between 0.09 and 0… more

A-Dependence of Deep-Inelastic Electron Scattering From Nuclei

Description: The deep inelastic electron scattering cross sections per nucleon sigma/sub A/ for d, He, Be, C, Al, Ca, Fe, Ag, and Au were measured in the kinematic range 0.09 less than or equal to x less than or equal to 0.9 and 2 less than or equal to Q/sup 2/ less than or equal to 15 (GEV/c)/sup 2/ using electrons with energies ranging from 8 to 24.5 GeV. The ratio sigma/sub A//sigma/sub d/ is consistent with unity in the range 0.1 < x < 0.3. For 0.3 < x < 0.8, the ratio decreases logarithmically with ato… more
