H. Güven, K. Bozkurt, E. Khan, and J. Margueron
Multistrange Ca, Sn, and Pb hypernuclei with ΛΛ
pairing interaction are investigated within the
Hartree-Fock-Bogoliubov approach. The unknown ΛΛ
pairing strength is calibrated to match with the maximal value for
the prediction of the Λ
pairing gap in uniform matter for densities and isospin
asymmetries equivalent to those existing in multi-Λ
hypernuclei. In this way, we provide an upper bound for the
prediction of the Λ
pairing gap and its effects in hypernuclei. The condensation
energy is predicted to be about 3 MeV as a maximum value, yielding
small corrections on density distributions and shell structure. In
addition, conditions on both Fermi energies and orbital angular
momenta are expected to quench the nucleon-Λ
pairing for most of hypernuclei.
