Photoproduction of phi meson off deuteron near threshold

Abstract

We discuss coherent and incoherent $\varphi$ meson photoproduction off the deuteron at low energy and small momentum transfer with the aim to check whether the recent experimental data need for their interpretation the inclusion of exotic channels. Our analysis of the differential cross section and spin-density matrix elements shows that the existing data may be understood on the base of conventional dynamics. For a firm conclusion about a possible manifestation of exotic channels one has to improve the resolution of the data with providing additional information on channels with spin- and double-spin flip transitions being sensitive to the properties of the photoproduction amplitude in $\gamma p$ and $\gamma D$ reactions.
