Near-threshold $\omega$ and $\varphi$ meson productions in $pp$ collisions

K. Tsushima, K. Nakayama

Using a relativistic effective Lagrangian at the hadronic level, near-threshold $\omega$ and $\varphi$ meson productions in proton proton ($pp$) collisions, $pp\to pp\omega /\varphi$, are studied wit…
