Under the assumption that production of the charmed vector meson ${D}^{*}$ is important in the charm threshold region, the soft cascade pion (photon) from ${D}^{*}\ensuremath{\rightarrow}D\ensuremath{\pi}$ (${D}^{*}\ensuremath{\rightarrow}D\ensuremath{\gamma}$) for ${M}_{{D}^{*}}\ensuremath{-}{M}_{D}g{M}_{\ensuremath{\pi}}$ (${M}_{{D}^{*}}\ensuremath{-}{M}_{D}l{M}_{\ensuremath{\pi}}$) could serve as a very useful clue for charmed particles. Also the pions produced in ${e}^{+}{e}^{\ensuremath{-}}$ 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.
