Fermi Motion Corrections for Deep Inelastic Muon Scattering on Nuclei at Large Q exp 2

摘要

Fermi motion corrections for deep inelastic cross section on carbon nuclei at 300 GeV energy of primary muons have been calculated to obtain qualitative estimates in HA-4 experiment kinematic region. The calculations have been performed in the nonrelativistic approach using incoherent approximation. The retios between structure functions of the nucleus and free nucleons have been found at Q exp 2 > 10(GeV/c) exp 2 . The calculations indicate that the Fermi motion produces the average shift of about 20 percent in kinematic variables x and nu /sub mu / and corrections for the cross sections exceed 30 percent for the x > 0.7 region. Thus the interpretation of experimental data should include Fermi motion in nuclei. (Atomindex citation 11:507452)
