Possible existence of ϕ3H, ϕ4H, ϕ4He, and ϕ5He nuclei
Abstract
Motivated by recent HAL QCD simulations of the ϕN interaction in the 4 S 3/2 channel and its modification in the 2 S 1/2 channel, we develop a first-principles few-body framework that embeds these potentials into configuration-space Faddeev–Yakubovsky equations. We predict bound ϕ 4 H , ϕ 4 He , and ϕ 5 He nuclei by performing calculations for ϕ -mesic ϕNNN and ϕNNNN systems. Both spin-dependent and spin-independent ϕN interactions are considered, leading to deeply and moderately bound states, respectively. The deeply bound states originate from the strong attraction in the 2 S 1/2 ϕN channel. Coulomb shifts of the binding energies are evaluated. Our findings provide the binding mechanism and demonstrate the importance of short-range ϕN attraction.
