Hidden Charm Exotics at BES III

• Applicant: Professor Dr. Klaus Peters
• Subject Area: Nuclear and Elementary Particle Physics, Quantum Mechanics, Relativity, Fields
• Term: from 2015 to 2020
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 271236083

The nature of the Y(4260) remains unclear despite or because of high precision data being available now. The resonance structure seems to be multifaceted and at least part of the structure is discussed in terms of exotic hadrons. Thus the goal of the project is to measure the decay channels of the Y(4260) region to clarify the structure and the properties of the underlying states with the potential to discover also so far unknown mesonic or baryonic states in the decays.In order to check for as many channels as possible in an unbiased way, the studies will be performed by analyzing (semi-)inclusive recoil-spectra of a couple of hadrons.
