Study of the Short Range Properties of Nucleons at Q 2 ≤ 12 GeV 2 Using d ( e , e ’ p ) n With CLAS 12 A Proposal to PAC 30
نویسندگان
چکیده
We are proposing to search for two possible QCD phenomena, Point Like Configurations (PLC) in the proton wave function, and modification of (deeply bound) nucleons involved in Short Range Correlations. We will use the exclusive d(e, e′p)n reaction, which is the most understood nucleon knockout reaction. This search will be an extension of the CLAS e6 experiment, which found no evidence for PLC at Q2 < 6 GeV2 or for nucleon modification (NM) at Q2 < 5 GeV2. Since both phenomena are expected to be strongly Q2 dependent, it is logical to continue these investigations at the higher Q2 region available with the CEBAF 12 GeV upgrade and the CLAS12 detector. The acceptance, resolutions and projected luminosity of CLAS12 are well suited for the proposed measurements. 32 beam time days will allow us to extend the PLC search up to Q2 = 12 GeV2, and the MN search up to Q2 = 10 GeV2 with high statistical precision.

A new proposal to the Jefferson Lab Program Advisory Committee (PAC34) Precision Measurement of the Neutron Magnetic Form Factor up to Q = 18.0 (GeV/c) by the Ratio Method
We propose to make a high-precision measurement of the neutron’s magnetic form factor, Gn M , at nine kinematic points: Q2 = 3.5, 4.5, 6.5, 8.5, 10., 12., 13.5, 16. and 18.0 (GeV/c)2. Little data on Gn M exists in this kinematic range and the existing data have large systematic uncertainties. In the proposed experiment, systematic errors are greatly reduced by the use of the “ratio” method in w...

متن کامل(A New Proposal to Jefferson Laboratory PAC 32) Precision Measurement of the Parity-Violating Asymmetry in Deep Inelastic Scattering off Deuterium using Baseline 12 GeV Equipment in Hall C
We propose a measurement of the parity-violating (PV) asymmetry in e− 2 H deep inelastic scattering (DIS) at Q 2 = 3.3 GeV 2 , W 2 = 7.3 GeV 2 and x = 0.34. The experiment will use the baseline 12 GeV Hall C spectrometer with a 40 cm liquid deuterium target and an 85 µA beam with 80% polarization. The predicted asymmetry is approximately 280 ppm at these kinematics, which is relatively large fo...

We have measured the asymmetry ALT ′ of the H(e, e‘p)n reaction in quasielastic kinematics at a beam energy of 2.56 GeV over a 4-momentum transfer range Q = 0.2 − 2.0(GeV/c) with the CLAS detector at Thomas Jefferson National Laboratory. We have performed a Monte Carlo simulation of the reaction in order to test the analysis code used to extract ALT ′ associated with the fifth structure functio...
