Exploring photoproduced meson states that decay K+K-π0 with an emphasis on events where the K+K- pair are from a0 decay
ORAL
Abstract
Mesons that have K+K-π0 decay products are potentially interesting as exotic states, however many non-exotics have the same decay products. On the way towards uncovering exotic meson states, a major goal of the GlueX experiment is to map the non-exotic light mesons into their respective nonets. This endeavor requires that methods utilized can sufficiently measure well known states. As a step towards uncovering the richness possessed for mesons that have K+K− 0 decay products is to search for low mass states decaying a0 0 that include K+K-π0 non-resonant contributions. Utilizing GlueX data for K+K-π0 photoproduction from the proton I will show a sharp peak in invariant mass K+K-π0 near the f1(1285) and η(1295) mass along with angular distribution of the decay products.
