Nuclear and Particle Physics Colloquium



Place:Room 513, Main Building, Beihang University

Time:10:00-11:00, April 1st, 2019

Title:Charmed baryon with negative parity

Speaker:Mr. Mao-Jun Yan


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).

About speaker:

Mr. Yan isa Ph.D.studentin ITP, CAS and works on hadron spectrum, particularlyCDD polesand dynamically generatedstates.
