2WBA.00001: Spectroscopy of Heavy Flavored Baryons Invited Speaker: John M Yelton Electron-positron annihilation data has long been a good laboratory for the study of charmed baryons. Furthermore, baryons containing strange quarks are also made in abundance, both directly in jets and in charmed baryon decays. Latest results on studies of charmed and strange baryons are presented, using data from the Belle detector which operated at the KEK-B electron-positron collider. |

2WBA.00002: Charmed baryons studied by pion emission decays Invited Speaker: Hideko Nagahiro We investigate the decays of the charmed baryons aiming at the systematic understanding of hadron internal structures based on the quark model by paying attention to heavy quark symmetry. We evaluate the decay widths from the pion emission for the known excited states, Λc(2595), Λc(2625), Λc(2765), Λc(2880), and Λc(2940). The decay properties of the lower excited charmed baryons are well explained, and several important predictions for higher excited baryons are given. We emphasize the importance of the branching ratios of Σc π and Σ*c π channels for the study of the nature of higher excited Λc baryons. Especially, we find that a small branching ratio of Λc(2880) might imply that a specific quark configuration dominates the Λc(2880) baryons. |

2WBA.00003: Spectroscopy of baryons with hidden and open flavors at LHCb Invited Speaker: Tomasz Skwarnicki The LHC provides large production rates for baryons with heavy quarks. The LHCb detector is well equipped to explore their spectroscopy. We will review the LHCb results on conventional and exotic baryons, including pentaquark studies. |
