A study of Lambda-Nucleon scattering using the CLAS detector
ORAL
Abstract
Previous data for the elastic scattering of Lambda baryons from the nucleon
dates back to the bubble chamber era as early as 1959. Using the high lumi-
nosity photon beam incident on a long (40 cm) liquid hydrogen target at Hall
B of Jefferson Lab, data was mined from the g12 experiment using the CLAS
detector. The detector was used to identify a final state with a proton in coinci-
dence with a scattered Lambda baryon. The initial Lambda, before scattering,
was produced via the γp → K +Λ reaction, for which the cross section is well
known. Using the known flux of Λ particles, preliminary measurements of the
Λ − p cross section will be presented. Future directions of related possibilities
for measuring hyperon-nucleon scattering at CLAS will be discussed.
