Photon-photon correlations in $e^{+}{e}^{-}\to F^{*}{\overline{F}}^{*}\to F{\gamma }_1\overline{F}{\gamma }_2$

The $F$ and $F^{*}$ mesons may be observed in $e^{+}{e}^{-}\to F^{*}{\overline{F}}^{*}\to F{\gamma }_1\overline{F}{\gamma }_2$. Kinematic constraints relating the energies and directions of the decay photons can be used to discriminate against backgrounds. This method may also be helpful for the discovery of new baryons and heavier mesons. Detailed studies of the photons' angular correlations can determine the $F^{*}{\overline{F}}^{*}$ production amplitudes.
