Investigation of electroproduction of $\varphi$ mesons off protons

Sang-Ho Kim, Seung-il Nam

We investigate $\varphi$-meson electroproduction off the proton target, i.e., ${\gamma }^{\ast }p\to \varphi p$, by employing a tree-level effective Lagrangian approach in the kinematical ranges of $Q^2$ =…
