Abstract

Under the assumption that production of the charmed vector meson D* is important in the charm threshold region, the soft cascade pion (photon) from D*→Dπ (D*→Dγ) for MD*-MD>Mπ (MD*-MD<Mπ) could serve as a very useful clue for charmed particles. Also the pions produced in e+e- collisions together with (strong-interaction-stable) charmed particles must obey energy equipartition. This strongly suggests other new heavy-quark thresholds and/or heavy-lepton production.
