Abstract
The f0(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 f0(1500) via decay into the K0
SK0
S channel using the CLAS detector. The reaction γp → fJp →
K0
SK0
Sp, where J = 0,2, was measured with photon energies from 2.7–5.1 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 fourmomentum 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.
