Query: Double $K_S^0$ Photoproduction off the Proton at CLAS   The $f_0$(1500) meson resonance is one of several contenders to have
significant mixing with the lightest glueball. This resonance is well
established from several previous experiments. Here we present the first
photoproduction data for the $f_0$(1500) via decay into the $K_S^0 K_S^0$
channel using the CLAS detector. The reaction $\gamma p$ -> $f_0 p$ -> $K_S^0
K_S^0 p$, where J = 0, 2, was measured with photon energies from 2.7 to 5.1
GeV. A clear peak is seen at 1500 MeV in the background subtracted invariant
mass spectra of the two kaons. This is enhanced if the measured 4-momentum
transfer to the proton target is restricted to be less than 1.0 GeV2. By
comparing data with simulations, it can be concluded that the peak at 1500 MeV
is produced primarily at low t, which is consistent with a t-channel production
mechanism.
