Particles with Internal Structure: The Geometry of Classical Motions and Conservation Laws

摘要

Classical models of elementary particles endowed with internal structure are constructed using the coadjoint orbit method. The geometry of minimal coupling is introduced and the Wong equations are recovered. Conservation laws are derived in the case of symmetric external Einstein-Yang-Mills fields. As a non trivial example, classical motions in a Belyavin-Polyakov-Schwarz-Tyupkin instanton's field are investigated. (Atomindex citation 13:676807)
