Measurement of masses of the ${\Xi }_c(2645)$ and ${\Xi }_c(2815)$ baryons and observation of ${\Xi }_c(2980)\to {\Xi }_c(2645)\pi$ %and observation of the ${\Xi }_c(2980)$ and observation of ${\Xi }_c(2980)\to {\Xi }_c(2645)\pi$

Belle Collaboration, T. Lesiak

We report a precise measurement of the masses of the ${\Xi }_c(2645)$ and ${\Xi }_c(2815)$ baryons using a data sample of 414 fb${}^{-1}$ collected by the Belle collaboration at the KEKB $e^+…
