Charm Spectroscopy via Electron-Positron Annihilation

Abstract

Electron-positron annihilation should be a rich source of charmed hadrons. The search for invariant-mass peaks together with the measurement of recoil-mass spectra is a technique that recently has borne fruit at SPEAR. We show how this technique may reveal the existence of the charmed baryons and of the excited states of the charmed mesons.
