Outline of Final Research Achievements |
Ordinary matter is made of light u and d quarks which are the two light elements in the standard model. Recent discoveries of many exotic hadrons containing heavy charm quarks and being difficult to explain their properties has opened a question about our understanding of the strong interaction physics. To solve this problem, in this research project, we have studied the simpler particles, charmed baryons, and their properties such as production rates and decay life times. Our achievements are: (1) We have predicted production rates of various charmed baryons, which contributes to the experimental plan at J-PARC. (2) We have clarified the relations between the structure and the rates of productions and decays, which has given a guideline for the future theoretical studies.
