Abstract

Space-time area laws play a fundamental role in modeling strongly interacting phenomena, such as in relativistic string models, QCD on the lattice, and in hadronization modeling. For the latter, an exact expression for relevant space-time areas related to the final state hadronic events for hadrons of any mass is calculated. Usage of this expression in the UCLA hadronization model helps validate its space-time area law (STAL) principle and unifies the treatment of heavy and light hadrons via a single fragmentation function.
