Threshold effects as the origin of $Y (4500)$ observed in $e^{+} e^{-} \to J / I ¨ K^{+} K^{-}$

Xiao-Yun Wang, Liu-Lin Wang, Xiao-Hai Liu +1

The BESIII collaboration has recently observed a resonant structure $Y (4500)$ in $e^{+} e^{-} \to J / I ¨ K^{+} K^{-}$ , whose origin remains unresolved. In this study, we analyze the cros…

Equation of state of spin-polarized nuclear matter in the relativistic Hartree-Fock method

Toi Tachibana, Kouichi Hagino, Kenichi Yoshida +1

We calculate the equation of state (EOS) of spin-polarized nuclear matter in the relativistic Hartree-Fock method. To this end, we employ the relativistic point-coupling model, wit…
