Possibility of ${\Sigma }_c(2800)$ and ${\Lambda }_c(2940{)}^{+}$ as $S$-wave $D^{(\ast )}N$ molecular states

Abstract

In this talk, we give a brief review of our work studying the possibility of ${\Sigma }_c(2800)$ and ${\Lambda }_c(2940{)}^{+}$ as $S$-wave $D^{(\ast )}N$ molecular states from QCD sum rules.

arXiv commenttalk given at the workshop on Hadron Nuclear Physics held from July 18 to 22, 2013 at Zhangjiajie, China
