“…With the upgraded ALICE apparatus and the larger data sample size expected [112], more interactions in the S = −2 sector (such as ΣΣ (I = 2)) could be tested experimentally in the upcoming LHC Run 3 and Run 4. In addition, studies of hypernuclei provide an promising alternative to extract information on the S = −2 baryon-baryon interactions from the photon-induced reactions at JLab or K − -induced reactions at J-PARC [18,113,114]. These studies will substantially advance our knowledge about the YN and YY interactions in the not-so-far future.…”

“…In particular, the interactions in the strangeness S = −2 sector (ΛΛ, ΞN, ΣΛ, ΣΣ) have gained more and more attention in many studies of current interest in nuclear physics and nuclear astrophysics, such as the H-dibaryon [1][2][3][4][5], double Λ and Ξ hypernuclei [6][7][8], and the so-called "hyperon puzzle" related to the maximum neutron star masses [9][10][11][12]. Different from the nucleon-nucleon case, where a large amount of high-quality scattering data exist, there are limited scattering data in the S = −1 sector due to the short life times of hyperons [13][14][15][16][17][18]. In the S = −2 sector, direct scattering data are almost non-existent except for a few reaction cross-sections of relatively poor quality [19].…”

We study the baryon-baryon interactions with strangeness S = −2 and corresponding momentum correlation functions in leading order covariant chiral effective field theory. The relevant low energy constants are determined by fitting to the latest HAL QCD simulations, taking into account all the coupled channels. Extrapolating the so-obtained strong interactions to the physical point and considering both quantum statistical effects and the Coulomb interaction, we calculate the ΛΛ and Ξ − p correlation functions with a spherical Gaussian source and compare them with the recent experimental data. We find a remarkable agreement between our predictions and the experimental measurements without introducing any free parameters, which demonstrates the consistency between theory, experiment, and lattice QCD simulations. Finally, we predict the ΣΣ (I = 2) interaction and corresponding momentum correlation function, which rules out the existence of a bound state in this channel. Future experimental measurement of the predicted momentum correlation function will provide a non-trivial test of not only SU(3) flavor symmetry and its breaking but also covariant chiral effective field theory.

“…Since, for an experimental observation of this multiplet we are limited to elastic scattering and heavy-ion correlations, there are very few states which we can currently access. An elastic scattering with either direct beams or rescattering of secondary beams within target material [21] can give us access to NN, ΛN, ΣN, ΞN scattering data. The latter reaction can be performed at the recently proposed KLF facility [22] with K L N → K + Ξ as a first step and ΞN → X as a second step reaction within a large target volume (or with similar methodology at J-PARC).…”

In recent years there has been tremendous progress in the investigation of bound systems of quarks with multiplicities beyond the more usual two- and three-quark systems. Experimental and theoretical progress has been made in the four-, five- and even six-quark sectors. In this paper, we review the possible lightest six-quark states using a simple ansatz based on SU(3) symmetry and evaluate the most promising decay branches. The work will be useful to help focus future experimental searches in this six-quark sector.

Subsequently, the E40 collaboration in the J-PARC Hadron Experimental Facility updated the measurements of the and scattering processes with 0.4 GeV/c GeV/c 2 [14,15,17], and the CLAS collaboration performed improved measurements on the cross section of the elastic scattering process with 0.9 GeV/c 2 < GeV/c 2 [16]. The uncertainties of all the above measurements are large.…”

The prospects to study hyperon-nuclei/nucleon interactions at BESIII and similar $e^+ e^-$ colliders are proposed in this work. Utilizing the large quantity of hyperons produced by the decay of 10 billion $J/\psi$ and 2.7 billion $\psi(3686)$ collected at BESIII, the cross sections of several specific elastic or inelastic hyperon-nuclei reactions can be measured via the scattering between the hyperons and the nucleus in the dense objects of BESIII detector. Subsequently, the cross sections of corresponding hyperon-nucleon interactions are able to be extracted with further phenomenological calculation. Furthermore, the interactions between antihyperon and nuclei/nucleon, including scattering and annihilation, can also be studied via the method proposed in this paper. The results will definitely benefit a lot the precise probe of the hyperon-nuclei/nucleon interactions and provide constraints for the studies of the potential of strong interaction, the origin of color confinement, the unified model for baryon-baryon interactions, and the internal structure of neutron stars. In addition, the desirable prospects of corresponding studies in the future Super Tau-Charm Factory (STCF) are discussed and estimated in this work.
