Photoproduction of the f(2)(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¯) 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 Ï mesons. Such a state would be expected to decay strongly to final states with charged pions due to the dominant decay ÏâÏ+Ï-, whereas decay to two neutral pions would likely be suppressed. Here, we measure for the first time the reaction γpâÏ0Ï0p, using the CEBAF Large Acceptance Spectrometer detector at Jefferson Lab for incident beam energies between 3.6 and 5.4 GeV. Differential cross sections, dÏ/dt, for f2(1270) photoproduction are extracted with good precision due to low backgrounds and are compared to theoretical calculations.
