The purpose of this research is to identify a single-Λ hypernucleus and its decay products which support to get more information about hyperon-nucleon interaction. Before performing the analysis of a single-Λ hypernucleus, first, we have deduced the density of emulsion by calibrating the range-energy relation using alpha decay events data from thorium series. It is very important for the mass reconstruction of hypernucleus events in nuclear emulsion. And we have reconstructed a single-Λ hypernucleus event by using the kinematical reconstruction for mesonic and non-mesonic decay modes. From the result of our analysis, we can uniquely identify that single-Λ hypernucleus is$ {}_\\Lambda ^9 B $and decay products are 4 He , 3 He, proton and neutron.

This double-blind study randomly assigned adults with obesity (or overweight and with one or more weight-related coexisting conditions) without diabetes to 68 weeks of once-weekly subcutaneous semaglutide (2.4 mg) or placebo, plus lifestyle intervention. Semaglutide therapy was associated with sustained, clinically relevant weight reduction.

We have investigated the single-pole nature of the detectable $\\Lambda(1405)$ in detail, by employing a chiral model having double poles of a $\\bar KN$–$\\pi \\Sigma$ coupled-channel $T$-matrix. The effects of the first pole and the second pole on the observed $\\pi \\Sigma$ mass spectrum in the $\\Lambda(1405)$ region have been analyzed almost separately. It is concluded that the first pole is responsible for both peak structures seen in the $T_{\\pi \\Sigma \\leftarrow \\bar KN}$($T_{21}$) and $T_{\\pi \\Sigma \\leftarrow \\pi \\Sigma}$($T_{22}$) invariant-mass spectra, and, due to an energy-dependent chiral interaction, the second pole provides continuum amplitudes affecting the shape of the peak structures of the first pole in the experimentally observable spectrum of $\\Lambda(1405)$.

The effective Λ-Λ interaction energies in s-shell double-Λ hypernuclei, ΛΛ6He, ΛΛ5He and ΛΛ5H have been investigated by solving three-body system (Λ + Λ + core) within the framework of coupled rearrangement channel Gaussian basis treatment. The Nijmegen soft-core potential models, NSC97d, NSC97e and NSC97f, have been applied for free-space Λ-Λ interaction. By taking into account the medium effects, it was adjusted to fit the experimental Λ-Λ interaction energies of ΛΛ6He (0.67 ± 0.17 MeV). The effective Λ-Λ interaction energies of ΛΛ5He are 0.92 MeV, 0.88 MeV, 0.86 MeV for each potential model and that of ΛΛ5H is 0.6 MeV for all potential modes. Moreover, the Λ-superfludity in the neutron star cores which is related to cooling process has also been investigated by applying our constructed effective Λ-Λ NSC97e potential of ΛΛ6He. It is found that Λ superfludity begins to appear when the interaction strength is 1.5 times more attractive than our constructed interaction. The Λ-superfluidity in the neutron star cores might occur at the hyperon percentage YΛ (1%–5%), and vanish at YΛ (15%– 20%).

For the capital sigma - capital sigma - alpha system we theoretically look into the possible existence of a quasi-bound state in the framework of Faddeev calculations. We are particularly interested in the state of total iso-spin T=2, because there is no strong conversion between Xi -N- alpha and $${\\Lambda-\\Lambda-\\alpha}$$ . An analytic continuation using the point method is applied to search the eigenvalue in the complex energy plane. In our results the capital sigma - capital sigma - alpha three-body system has two quasi-bound states (J super( ) pi = 0 super(+)) where, depending on the potential parameters in the Nijmegen NSC97 model potential, the energy ranges between -1.4 and -2.4 MeV and the level width is about 0.4 MeV for the ground state. In addition, we obtained the excited state at -0.15 MeV (width 4 MeV).

We have investigated theoretically a feasible nuclear reaction to produce light double- Lambda hypernuclei by choosing a suitable target. In the reaction from stopped Xi super(-) on super(6)Li target light doubly-strange nuclei, $${ one fourth _{\\Lambda\\Lambda}{\\rm H}}$$ and $${ similar to _{\\Lambda\\Lambda}{\\rm He}}$$, are produced: we have calculated the formation ratio of $${ one fourth _{\\Lambda\\Lambda}{\\rm H}}$$ to $${ similar to _{\\Lambda\\Lambda}{\\rm He}}$$ for Xi super(-) absorptions from 2S, 2P and 3D orbitals of Xi super(-)- super(6)Li atom by assuming a d- alpha cluster model for super(6)Li. From this cluster model the d- alpha relative wave functions has a node due to Pauli exclusion among nucleons belonging to d and alpha clusters. Two kinds of d- alpha wave functions, namely 1s relative wave function with a phenomenological one-range Gaussian (ORG) potential and that of an orthogonality-condition model (OCM) are used. It is found that the probability of $${ one fourth _{\\Lambda\\Lambda}{\\rm H}}$$ formation is larger than that of $${ similar to _{\\Lambda\\Lambda}{\\rm He}}$$ for all absorption orbitals: in the case of the major 3D absorption their ratio is 1.08 for ORG and 1.96 for OCM. The dominant low momentum component of the d- alpha relative wave function favors the $${ one fourth _{\\Lambda\\Lambda}{\\rm H}}$$ formation with a low Q value compared to the $${ similar to _{\\Lambda\\Lambda}{\\rm He}}$$ formation with a high Q value. We have also calculated momentum distributions of emitted particles, d and n, displaying continuum spectra for single- Lambda hypernuclei, $${ pound sterling _{\\Lambda}{\\rm H}}$$ and $${ one fourth _{\\Lambda}{\\rm He}}$$, and line spectra for the $${ one fourth _{\\Lambda\\Lambda}{\\rm H}}$$ and $${ similar to _{\\Lambda\\Lambda}{\\rm He}}$$ nuclei. Thus, our present theoretical analysis would be a significant contribution to experiments in the strangeness -2 sector of hypernuclear physics.
