Cusp-like structure in the $\gamma p \rightarrow K^+\Sigma^0$ cross section at low momentum transfer

Le résumé fourni par la source

Differential cross section data for $\gamma p \rightarrow K^+\Sigma^0$ has been measured at the BGOOD experiment for extremely forward angles. A three quarter drop in strength over a narrow range in energy and strong dependence on polar angle is observed at a centre of mass energy of 1900 MeV. Residing close to multiple open and hidden strangeness thresholds, the kinematics are consistent with threshold effects and exotic structure which may contribute to the reaction mechanism.
