Are anomalons still provocative: a summary of the present experimental situation

A number of experiments have shown that enlarged cross sections exist for projectile fragments which are emitted in relativistic heavy ion collisions. The present status of these investigations is reviewed and new detector techniques for anomalon search are discussed. Most experiments are compatible with an assumption that the anomalon effect is smaller than 3% and appears within distances shorter than about 2 cm from the parent reaction. 39 references
