Two-gluon production of $\varphi$ and ${\eta }^{\prime }$ mesons in proton-proton collisions at high energies

Anna Cisek, Antoni Szczurek

We discuss gluon-gluon mechanisms for production of mesons with hidden strangeness, such as ${\eta }^{\prime }$ and $\varphi$ meson, in proton-proton collisions at large energies. The $g^{\ast }{g}^{\ast }\to {\eta }^{\prime }$…
