The Photoproduction of $\Lambda $*(1520)

ORAL

Abstract

The photoproduction of $\Lambda $*(1520) on both the proton and neutron have been studied by using CLAS eg3 run data set. The reactions are $\gamma $d $\to $ K$^{+}\Lambda $*(n) and $\gamma $d $\to $ K$^{0}\Lambda $*(p) with $\Lambda $* $\to $ pK$^{-}$. Both preliminary total and differential cross sections have been extracted in the photon energy region 1.75GeV $<$ E$_{\gamma } \quad <$ 5.50GeV. This is the first time that the photoproduction of $\Lambda $*(1520) on the neutron is reported. And we will extend the results on the proton to higher energies than in previous studies.
