“…This can make an unbound normal nucleus bound (viz., the nucleus 9 Li + n is unbound, but 9 Li+Λ is bound), and may even lead to the production of exotic nuclei beyond the normal drip lines. Hence hypernuclei are an experimental testing ground to study how a system of up-and down-quarks changes towards the full flavor SU (3), when strange quarks are added implicitly through hyperons.…”

Neutron dripline calculations for both magnesium nuclei and magnesium + Λ hypernuclei have been carried out in a microscopic framework using a chiral effective model. The results are compared with two other relativistic mean field models, SPL-40 and NL3. All three models describe the Λ separation energy of known hypernuclei adequately. The extrapolation to the driplines for moderately heavy hypernuclei are found to be strongly model-dependent.

“…The binding energy of various hypernuclei has already been measured. To increase this number, experimental searches for neutron rich hypernuclei have been carried out at JPARC, Japan [1], [2], and JLab, USA [3], [4]. Also, there are proposed experiments like HypHI [5], [6] at GSI, Darmstadt, Germany and NICA [7] in Dubna, Russia.…”

The associated photoproduction of [Formula: see text] from the proton in the low energy region is studied using an isobar model in which the nonresonant contributions are obtained from the nonlinear sigma model with chiral SU(3) symmetry which predicts, in a natural way, the contact term with its coupling strength along with the coupling strengths of the various Born terms predicted by the nonlinear sigma model. The present model is an extension of the nonlinear sigma model with chiral SU(2) symmetry, used earlier to study the photo, electro, and neutrino productions of pions. In the resonance sector, the contributions from the well established nucleon resonances ([Formula: see text]) in the [Formula: see text] channel, the hyperon resonances ([Formula: see text]) in the [Formula: see text] channel, and the kaon resonances ([Formula: see text] and [Formula: see text]) in the [Formula: see text] channel having spin [Formula: see text] and mass [Formula: see text][Formula: see text]GeV with a significant branching ratio in [Formula: see text] decay mode, have been considered. The strong and electromagnetic couplings of the [Formula: see text] channel nucleon resonances are taken from experiments while the couplings for the resonances in the [Formula: see text] and [Formula: see text] channels are fitted to reproduce the current data on the associated photoproduction of [Formula: see text] in this energy region. The numerical results are presented for the total and differential cross-sections and are compared with the available experimental data from CLAS and SAPHIR as well as with some of the recent theoretical models.
