| Outline of Final Research Achievements |
The smallest component of known material is a quark. But, a theory of quarks anticipates additional unknown materials. I investigated mass spectrum including charm quarks by numerical simulations.
This study shows that the baryon mass spectrum including one charm quark agrees with experiments. On the other hand, the Ξcc(3520) baryon mass which includes two charm quarks significantly deviates from the reported experimental value. It suggests the experimental value is not correct. The true value is predicted to be 100 MeV higher. In addition, spectrum of other undiscovered charmed baryon comprised of two and three charm quarks is predicted in 2% precision.
