Charm Baryon Spectroscopy at J-PARC†

Introduction†

Why charmed baryons?

What are essential degrees of freedom in baryons?

This is one of the most fundamental questions in hadron physics. Quarks are thought to be elementaly particles. A single quark cannot be kept separated from a hadron and is confined in a hadron.

The constituent quark model (CQM) well describes the properties of hadrons, but sometimes fails in excited states. There remain many undiscovered states in the CQM, which is a long-standing puzzle, known as the so-called missing resonance problem. The mass order of the resonance baryons

Collaboration†

This activity is an international collaborative research project of the Reseach Center for Nuclear Physics (RCNP), Osaka university.
The project is based also on the research collaboration under the MOU between RCNP, IPNS/KEK, and the J-PARC center.
