Abstract

We calculate the cross section and the beam asymmetry for exclusive photoproduction of charmed particles near threshold (gamma + p --> Lambda (+)(c) (D-0) over bar), in the framework of an effective Lagrangian model. We discuss the sensitivity of these observables to the magnetic moment of the Lambda (c) baryon and of the coupling constant in the p Lambda D-c vertex. We show that exclusive measurements allow, in principle, to determine the magnetic moments of charmed baryons. (C) 2001 Published by Elsevier Science B.V.
