| Title | Photoproduction of the f2(1270)meson using the CLAS detector | ||||
| Abstract | The quark structure of the f2(1270) meson has, for many years, been assumed to be a pure quark-antiquark (qq-bar) resonance with quantum numbers JPC = 2++. Recently, it was proposed that the f2(1270) is a molecular state made from the attractive interaction of two r-mesons. Such a state would be expected to decay strongly to final states with charged pions, due to the dominant decay r -> p+p-, whereas decay to two neutral pions would likely be suppressed. Here, we measure for the first time the reaction gr -> p+p-r, using the CLAS detector at Jefferson Lab for incident beam energies between 3.6-5.4 GeV. Differential cross sections, ds=dt, for f2(1270) photoproduction are extracted with good precision, due to low backgrounds, and are compared with theoretical calculations. | ||||
