Description

The lattice QCD analysis of the HAL QCD Collaboration has recently derived
spin $3/2$ $N-\varphi$ potential based on the $\left(2+1\right)$-flavor lattice QCD simulations near the physical point $m_{\pi }\simeq 146.4$ MeV and $m_K\simeq 525$
MeV on a large lattice space- time volume $\simeq {\left(8.1\text{fm}\right)}^4$.
We looked closely at phi-meson $\left(\varphi \right)$ and two nucleons $\left(NN\right)$ system making use of the HAL QCD Collaboration $N-\varphi$ interactions and the realistic $NN$ Malfliet-Tjon (MT) potential.
The developed Faddeev three-body calculations for $(I)J^{\pi }=(0)2^{-}$ $\varphi -d$ system in maximum spin lead to ground state binding energy of about $7$ MeV and a matter radius of about $8$ fm. Our results indicate the possibility of the formation of new nuclear clusters.
