UCLA Space-Time Area Law Model: A Persuasive Foundation for   Hadronization
  From the studies of rates and distributions of heavy quark mesons we have developed additional evidence that hadron formation is dominantly controlled by a Space-Time Area Law, an approach suggested by both non-perturbative QCD and Relativistic String Models.
