Centauro- and anti-Centauro-type events
  Assuming that leading particles in high-energy hadronic and nuclear collisions become sources of a classical pion field, we show that the direct production of pions favors Centauro (mainly charged) events and that the production of pions through the $ \rho$-type channel favors anti-Centauro (mainly neutral) events. We also observe a strong negative neutral-charged correlation in both cases.
