The Jefferson Laboratory in Virginia hosts two experiments (GlueX and CLAS12) dedicated to the study of meson interaction. These experiments are searching for exotic mesons produced by photons on a hydrogen target. The most promising signal of an exotic meson, in this case a state composed of a q qbar together with an extra gluon, has been observed in the P-wave of the eta+pi0 final state. However the confirmation of this discovery requires a comparison between theoretical predictions and experimental observables.
The project consists in studying the reaction gamma + p --> eta + pi0 + p at high energies and developing a model for the production of exotic meson in this reaction (to be compared with GlueX preliminary data)
