Group: TJNAF CLAS

The experiment:

At TJNAF a photon beam with energies up to 5.4 GeV was shot on a liquid hydrogen target. (Re)scattering reactions were detected with the CLAS detector. The resulting data of the g12 run was mined for elastic Λp events.

The data:

Λ p → Λ p Total cross section (SGT)
Based on 71 events in the range 500 MeV/c - 15 GeV/c
