Multiple hadron production by 14. 5 GeV electron and positron scattering from nuclear targets

Multiple hadron production by 14. 5 GeV electron and positron scattering from nuclear targets

Multiple proton and pion electroproduction from nuclei are studied. Final states including at least two protons produced by the interaction of 14.5 GeV electrons and positrons with light nuclei (mainly [sup 12]C and [sup 16]O) have been measured, and compared with analogous data from [sup 40]Ar.

Description
Summary:Multiple proton and pion electroproduction from nuclei are studied. Final states including at least two protons produced by the interaction of 14.5 GeV electrons and positrons with light nuclei (mainly [sup 12]C and [sup 16]O) have been measured, and compared with analogous data from [sup 40]Ar. Scattered electrons and positrons were detected in the energy transfer range from 0.2 to 12.5 GeV, and four-momentum transfer squared range from 0.1 to 5.0 GeV[sup 2]/[ital c][sup 2]. Phenomenological characteristics of the secondary hadron production cross sections such as temperature and velocity of the effective source of hadrons were found to be dependent on energy transfer to the nucleus and independent on the four-momentum transfer squared at energy transfers greater than 2 GeV.
