Search for Hidden-Charm Pentaquark with CLAS12

ORAL

Abstract

LHCb recently announced the discovery of two exotic structures in the J/ψ+p decay channel, which have been referred to as charmonium-pentaquark states. Resolving differences between models for these states, clarifying the nature of the discovered hidden-charm pentaquark peaks, and discovery of any similar states with other quantum numbers, will require further experimental studies. It is natural to expect that such pentaquark states should be produced in the photoproduction process γ+p-> Pc -> J/ψ+p, where they will appear as s-channel resonances at photon energy around 10 GeV. The energy and luminosity of the Jefferson Lab CLAS12 photon beam will permit detailed studies of the production and decay properties of such pentaquark resonances. This presentation will discuss a search for these pentaquark states which is currently underway with CLAS12.
