Search for Strangeonia in Photoproduction using CLAS
The HyCLAS experiment at Jefferson Lab is a program to search for new and unusual mesons produced via photoproduction. The strangeonia sector is poorly known and a main component of this program is a search for new strangeonium states. The reaction gamma p-->p phi eta is an ideal channel to look for strangeonium states due to the strangeness content of both the phi and eta. The data was acquired at the JLAB CLAS facility using a 4-5.5 GeV tagged photon beam. The phi meson is identified via the K+K- decay. The recoil proton is observed in the CLAS spectrometer and the eta meson is identified through the missing mass. Also of interest is the search for strangeonia decaying to phipi0 and phiomega. These channels are OZI suppressed for qq-bar mesons and an observation of a meson decaying to these channels would provide a strong evidence of mesons beyond qqa. Preliminary results describing the data quality, kinematics and dynamics will be shown.
