All have reported candidate events; the author describes here the gravitational microlensing effect, the specifics of each experiment and discusses their present results.

From an analysis of the distributions of MX2 within the framework of a triple Regge formalism we obtain the effective Regge trajectories corresponding to varrho, K or K* and nucleon exchange.

The main results concern the production mechanisms of the overlineK∗(890) and overlineK∗(1420) . We also extract the s-wave component of the overlineKπ system as a function of mass.
