Hypertriton production yield in LHC pp collisions, described by nuclear coalescence, confirms its halo structure with a Lambda separation of 9.54 fm from the deuteron core.
Including hyperons reduces maximum neutron-star mass by 0.05-0.10 solar masses and increases radius at 1.4 solar masses by 0.5-0.8 km across all models while keeping every equation of state consistent with the 2-solar-mass limit.
