Prof. Hiyama Emiko (Kyushu University)Abstract SubmissionSince the observation of Ξ hypernucleus, Kiso event, it is requested what kinds of Ξ hypernuclei should be observed as bound states in the future at J-PARC. As light Ξ hypernuclei, I propose to perform a search experiment of nnΞ and nnnΞ systems using 3He and 4He targets. In this conference, from the observation what kinds of ΞN part we can get to extract information.Go to contribution page

Dr Masahiro Yoshimoto (Gifu University)Abstract SubmissionNuclear emulsion is a tracking detector with sub-micron spatial resolution. The nuclear emulsion has a potential to measure binding energies of mirror hypernuclei such as $_{\Lambda}^{4}$H and $_{\Lambda}^{4}$He directly. The binding energies provide valuable information for charge symmetry braking (CSB) in $\Lambda$-N interaction. In the nuclear emulsion experiment in the 1960s and...Go to contribution page

Dr Alessandro Feliciello (INFN - Sezione di Torino)Abstract SubmissionIn the last decade several targetted, well focussed experiments provided a remarkable amount of high quality information about $s$-, $p$- and, very recently, $sd$-shell $\Lambda$-hypernuclei. Their results contribute to significantly improve our knowledge of the field. However, some ''surprising'' outcomes came from non-dedicated large apparatus like STAR and ALICE, originally intended for...Go to contribution page

Dr Franco Garibaldi (INFN)Abstract SubmissionThe recent observation of 2-solar-mass neutron-stars rules out most of the current models for the hyperonic matter equation of state which favour the appearance of hyperons in the neutron star interior but predict maximum masses (Mmax) incompatible with present data. This problem, known as the hyperon-puzzle, is presently a subject of very active research. A solution to it necessarily...Go to contribution page

Dr Albert Feijoo Aliau (Nuclear Physics Institute, 25068 Rez, Czech Republic), Prof. Volodymyr Magas (University of Barcelona), Prof. Àngels Ramos (University of Barcelona)Abstract SubmissionThe plausible explanation of the $\Lambda(1405)$ resonance as a molecular state arising from coupled channel meson-baryon re-scattering in the strangeness $S=-1$ sector employing the lowest order chiral Lagrangian is one of the most important successes of Unitaritzed Chiral Perturbation Theory (UChPT). Despite this theoretical breakthrough, the aim for more precise calculations led the...Go to contribution page

Dr Stefano Gandolfi (Los Alamos National Laboratory)Abstract SubmissionRecent advances in experiments of the symmetry energy of nuclear matter and in neutron star observations yield important new insights on the equation of state of neutron matter at nuclear densities. In this regime the equation of state of neutron matter plays a critical role in determining the mass-radius relationship for neutron stars. We show how microscopic calculations of neutron matter,...Go to contribution page

Prof. Luis Augusto Trevisan (Universidade Estadual de Ponta Grossa)Abstract SubmissionIn the Present work, the effects of the nonextensivity are considered in a model to obtain the polarized structure function for the proton and the neutron, including the strange contribution for each one. Any type of symmetry is considered as a consequence of the experimental data involved. Therefore, we may show that the total amount of strange quarks is proton is different from the neutron,...Go to contribution page

Dr madhumita dhar (Balurghat College)Abstract SubmissionA revised version of SU(3) based meson exchange interaction model has been developed in this work to investigate vacuum hyperon-baryon interaction for the SU(3) octet. The main focus on revising the other existing OBE model was in reducing the number of free parameter of the model since the number of data available are very less and to have a qualitative knowledge on the extent of SU(3)...Go to contribution page

manami fujita (tohoku Univ)Abstract SubmissionStudying hyperon-nucleon interaction is necessary for more general understanding of nuclear force. We can extend the NN interaction with the isospin SU(2) symmetry to the baryon-baryon interactions with the flavor SU(3) symmetry. For the S=-2 sector, however, experimental data are very limited. Especially there are almost no data for the ΞN interaction. To investigate the S=-2 systems, we...Go to contribution page
