“…On the experimental side, there are very few data in theŜ = −2 sector, coming from the inelastic Ξ − p → ΛΛ cross section at a lab momentum of around 500 MeV/c, and from the elastic Ξ − p → Ξ − p and inelastic Ξ − p → Ξ 0 n cross sections for lab momenta in the range of 500 -600 MeV/c [5][6][7]. Thus, the relevant information we have is indirect and comes from double-Λ hypernuclei.…”

We perform a coupled-channel calculation of the H dibaryon within a chiral constituent quark model. The problem is solved within a quark model constrained by the experimental data of strangeness -1 and -2 two-baryon systems. We examine in detail the role played by the different contributions of the interacting potential as well as the number of coupled channels considered. Special attention has been payed to the parameter dependence, flavor symmetry breaking and spatial configurations. The value extracted for the binding energy of the H dibaryon, being compatible with the restrictions imposed by the Nagara event, falls within a plausible extrapolation of recent lattice QCD results.

“…Table 1. There is scarce experimental information on these channels [24] that could be used to fix this LEC, but it turned out that the quality of the existing data do not really allow to constrain its value reliably [14]. Our results for the S = −2 sector are shown in Figs.…”

Abstract. I report on recent progress in the description of baryon-baryon systems within chiral effective field theory. In particular, results for the hyperon-nucleon and hyperon-hyperon interactions as well as for strangeness S = −3 to −4 baryon-baryon systems, obtained to leading order are discussed. Preliminary results for the hyperon-nucleon interaction to next-to-leading order are presented.

“…Unstable channels such as the I = 0 NΞ, which can decay into ΛΛ via the strong interaction, will be discussed later. In addition, experimentally, not much information has been available on the NΞ interaction except for a few studies: a recent report gives the upper limit of elastic and inelastic cross sections [36] while earlier publications suggest weak attractions of Ξ− nuclear interactions [37,38,39]. The Ξ−nucleus interactions will be soon studied as one of the day-one experiments at J-PARC[40] via (K − , K + ) reaction with a nuclear target.…”

Progress on the potential method, recently proposed to investigate hadron interactions in lattice QCD, is reviewed. The strategy to extract the potential in lattice QCD is explained in detail. The method is applied to extract N N potentials, hyperon potentials and the meson-baryon potentials. A theoretical investigation is made to understand the origin of the repulsive core using the operator product expansion. Some recent extensions of the method are also discussed.
