"Phi meson photoproduction at CLAS"
ABSTRACT:
Phi meson photoproduction cross section in its neutral decay mode is measured for the reaction gamma p → p (KSKL). The experiment is performed with a tagged photon beam of energy 1.6 -3.6 GeV incident on a liquid hydrogen target of the CLAS at Thomas Jefferson National Accelerator Facility. The final state is identified via reconstruction of KS in the invariant mass of two oppositely charged pions and by requiring missing particle in the reaction gamma p → p KS X to be KL. Presented results significantly enlarge the existing data on phi meson photoproduction. These data, combined with the data from the charged decay mode, will help to constrain different mechanisms of the phi photoproduction.
