| Title | Coherent Photoproduction of proton anti-proton pair on deiterium with CLAS | ||||
| Abstract | In this project coherent production of proton anti-proton pairs on deuterium with a high energy bremsstrahlung photon beam is studied. The main objective is to study claims of several groups on existence of two meson states, masses ~2.02 GeV and ~2.2 GeV. Coherent production on deuterium has an advantage compared to the production on hydrogen. It will eliminate ambiguities in the production mechanism, since only t-channel production of (pp-bar) is allowed. <br /><br /> Data from the CLAS detector at Jefferson Lab (TJNAF) has been analyzed. The experiment run in 2004-2005 with tagged bremsstrahlung photon beam of up to 5.5 GeV and a 40 cm long liquid deuterium target. During the experiment the CLAS torus magnet polarity was set to bend negatively charged particles outwards from the beam line. During the run the main trigger was tagger hodoscopes in relevant energy region in coincidence with three prong event in CLAS. The reactions ¿d->pp-bar-d, ¿d->pi+pi-d, and ¿d->K+K-d in fully excl | ||||
