There is little known about baryon-antibaryon photoproduction mechanisms. Three reactions, γp→ppp¯, γp→ppn¯π−, and γp→pnp¯π+ have been investigated for the photon energy range of 3.95-5.45 GeV. The data were from the g12 run period taken with the CLAS detector using a liquid hydrogen target in Hall B at Thomas Jefferson National Accelerator Facility. This experiment had high statistics, with an integrated luminosity of 68 pb−1. General features of the data and preliminary cross sections are presented.
