Title: Photoproduction of the f 2 ( 1270 ) Meson Using the CLAS Detector

Abstract

The quark structure of the f 2 ( 1270 ) meson has, for many years, been assumed to be a pure quark-antiquark (q$$\bar{q}$$) resonance with quantum numbers JPC = 2++ . Recently, it was proposed that the f 2 ( 1270 ) is a molecular state made from the attractive interaction of two ρ mesons. Such a state would be expected to decay strongly to final states with charged pions due to the dominant decay ρ → π+ π- , whereas decay to two neutral pions would likely be suppressed. Here, we measure for the first time the reaction γp → π0π0p, using the CEBAF Large Acceptance Spectrometer detector at Jefferson Lab for incident beam energies between 3.6 and 5.4 GeV. Differential cross sections, dσ/dt , for f 2 ( 1270 ) photoproduction are extracted with good precision due to low backgrounds and are compared to theoretical calculations.
