Two recently discovered excited charm baryons are studied within the
framework of Heavy Hadron Chiral Perturbation Theory. We interpret these new
baryons which lie 308 \MeV and 340 \MeV above the Λc as I=0
members of a P-wave spin doublet. Differential and total decay rates for their
double pion transitions down to the Λc ground state are calculated.
Estimates for their radiative decay rates are also discussed. We find that the
experimentally determined characteristics of the Λc∗ baryons may be
simply understood in the effective theory.Comment: 16 pages with 4 figures not included but available upon request,
