Parsing the Path Integral

The Feynman path integral offers some promise towards an understanding of quantum phenomena in terms of histories in ordinary spacetime (rather than instantaneous states in configuration space). The path integral's symmetries are also arguably aligned against the standard division of quantum processes into dynamical time-evolution followed by a probabilistic collapse. This talk will discuss the option of an alternate parsing of the single-particle path integral into special groups of paths. Each group can be assigned a positive probability, and there is no interference between groups (only paths in a given group interfere with each other). If each special group of particle paths is then re-interpreted as flow lines of a realistic field, this indicates a possible one-real-field-history interpretation of the path integral. See K.B.
