Title:Charmed baryon with negative parity
Speaker:Mr. Mao-Jun Yan
Wetake NLO interaction in ChPT and CDD pole (p-wave excitation of heavy diquark)into consideration and show a richer spectrum of doubly charmed baryon withJ^P=1/2^- in I=0, 1/2 sectors. We give an interesting explanation aboutspectrum 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).
Mr.Yan is a Ph.D. student in ITP, CAS and works on hadron spectrum, particularly CDDpoles and dynamically generated states.
