abstract

The developed Faddeev three-body equations are solved to search for bound-state solutions of a phi-meson $ \left(\phi\right) $ and two nucleons $ \left( \textrm{NN} \right) $ system. The newly published spin $ 3/2 $ $ \textrm{N-\ensuremath{\phi}} $ potential based on the $ \left(\textrm{2+1}\right) $-flavor lattice QCD simulations near physical point, and realistic $ \textrm{NN} $ Malfliet-Tjon (MT) potential, are employed. Our numerical calculations for $ (I)J^{\pi}=(0)2^{-}$ $ \phi\textrm{-d} $ system in maximum spin leads to ground state binding energy of about $ 7 $ MeV and a matter radius of about $ 8 $ fm. Our results indicates the possibility of the formation of new nuclear clusters.

    hep-ph 2026-08 conditional novelty 4.0 of 10

    A momentum-space Faddeev calculation with Malfliet-Tjon and HAL QCD potentials predicts phi-nucleon-nucleon bound states and no J/psi-nucleon-nucleon bound state.
