4WKB.00001: Theoretical study of medium-heavy Λ hypernuclei Invited Speaker: Atsushi Umeya In the recent experimental studies of hypernuclei with a strangeness S=-1, the γ-ray measurements with Ge detector arrays have been performed to clarify the fine structures of low-lying energy levels for p-shell hypernuclei. In the J-PARC E13 experiment, the γ-ray measurements have been analyzed for low-lying states of 19ΛF as a gateway to sd-shell and heavier systems. Moreover a series of recent (e, e' K+) reaction experiments from the Jefferson Laboratory provide high-resolution data of the low-lying energy levels for p-shell hypernuclei. These data are quite helpful in better understanding of hyperon-nucleon interactions, though the data are still limited to about ten hypernuclear species. |

4WKB.00002: Recent progress of hyperon-nucleon scattering experiment and future prospects for ΛNN interaction study at J-PARC Invited Speaker: Koji Miwa Scattering experiments involving a hyperon and a proton are the most effective way for investigating 2 body hyperon–nucleon (YN) interactions, as is the case in various intensive studies on pp and np scattering for understanding nucleon–nucleon (NN) interactions. Scattering observables, such as differential cross sections and spin observables, are essential experimental inputs for constructing theoretical frameworks of YN interactions assuming a broken flavor SU(3) symmetry. |

4WKB.00003: Structure of Xi hypernuclei and Xi N interaction Invited Speaker: Emiko Hiyama It is important to study Xi N interaction from the structure of Xi hypernuclei. Recently, we observed Xi hypernucleus as a bound state. |

4WKB.00004: The Role of Hyperons in Neutron Stars Invited Speaker: Anthony W Thomas Studies of the equation of state of dense matter in beta-equilibrium suggest that hyperons must play a role. On the other hand, the appearance of hyperons has the effect of lowering the rate of increase in pressure as the density rises. This creates challenges for hadronic models to produce neutron stars with the largest masses observed. We will review recent work on the inclusion of hyperons in the theoretical calculations of neutron star properties, including the possibility of new short-distance forces and a potential transition to quark matter. |
