Title:Charmed baryon with negative parity

Speaker:Mr. Mao-Jun Yan

Abstract:

We take NLO interaction in ChPT and CDD pole (p-wave excitation of heavy diquark) into consideration and show a richer spectrum of doubly charmed baryon with J^P=1/2^- in I=0, 1/2 sectors. We give an interesting explanation about spectrum of singly charmed baryon below 3.0 GeV with the help of two CDD poles, one is HQSS conserved and the other one is heavy quark spin symmetry broken. \Omega(2012) decaying to \Omega \pi^0 is applied to study structure of \Omega(2012).
