Abstract

We discuss the physics case for a new experimental setup that consists of the Crystal Ball multiphoton spectrometer and the CLAS12 forward detector installed at the tagged photon beam of Hall-B at JLab. The proposed apparatus will provide nearly 4π sr coverage and good energy and angular resolution for photons and protons allowing a detailed high statistics investigation of the reactions with multiple photons. Such setup can be used to investigate the spectrum of doubly-strange Ξ via their neutral decays, test C, CP, and T invariance in the neutral and charged decays of η and η′ perform precise measurements of the Dalitz and double Dalitz decays of pseudoscaler and vector mesons, etc. Such data may also shed new light on the existence and the properties of the earlier claimed light exotic mesons.
