Abstract

The beam-spin asymmetry, Σ, for the reaction γd→pn has been measured using the CEBAF Large Acceptance Spectrometer (CLAS) at the Thomas Jefferson National Accelerator Facility (JLab) for six photon-energy bins, between 1.1 and 2.3 GeV, and proton angles in the center-of-mass frame, θc.m., between 25∘ and 160∘. These are the first measurements of beam-spin asymmetries at θc.m.=90∘ for photon-beam energies above 1.6 GeV, and the first measurements for angles other than θc.m.=90∘. The angular and energy dependence of Σ is expected to aid in the development of QCD-based models to understand the mechanisms of deuteron photodisintegration in the transition region between hadronic and partonic degrees of freedom, where both effective field theories and perturbative QCD cannot make reliable predictions.

Abstract

Measurement of the semi-inclusive pi+ electroproduction off the proton, performed with CLAS detector at Jefferson Lab, has been presented. The obtained fully-differential cross sections, including the azimuthal angle between hadronic and leptonic planes, phi, allowed us to separate the phi-dependent terms. While, the phi-independent part of the cross section was found to be in good agreement with current fragmentation pQCD calculations., Comment: 3 pages, 2 figures, to appear in proceedings of Lomonosov 14th conference

Abstract

The inclusive inelastic electron scattering o the proton was measured at five different beam energies 1.5, 2.5, 4.0, 4.2 and 4.4 GeV. The data were taken, during February-March 1999, on a liquid hydrogen target with the CLAS detector installed in Hall-B of the Thomas Jefferson National Accelerator Facility (TJNAF). The obtained high statistics and high precision data appear to be in good agreement with previously measured world data and permit to integrate experimental values of F{sub 2} over x at fixed Q{sup 2} , allowing for the first time the evaluation of its experimental moments at low and moderate values of Q{sup 2} . In a combined analysis of CLAS and world data, the Q{sup 2} -evolution of the experimental moments was explored in the range from 0.3 up to 100 GeV{sup 2} . This offered a unique possibility to trace changes of the proton structure function from hard DIS down to the non-perturbative regime through the transition region, which is of particular interest for the TJNAF physics program. The obtained experimental moments allowed to perform a separation between the leading twist, calculable in the framework of the perturbative QCD (pQCD), and higher twists, treated effectively. A comparison with theoreticalmore » predictions based either on lattice QCD simulations or obtained within models of the nucleon structure may represent an important test of our understanding of the nucleon structure as observed at large wavelengths.« less
