Query: Strong one-pion decay of ground state charmed baryons   We evaluate the widths for the strong decays $\Sigma_c\to\Lambda_c \pi$,
$\Sigma_c^*\to\Lambda_c \pi$ and $\Xi_c^{*}\to\Xi_c \pi$. The calculations have
been done within a nonrelativistic constituent quark model with wave functions
that take advantage of the constraints imposed by heavy quark symmetry. Partial
conservation of axial current hypothesis allows us to determine the strong
vertices from an analysis of the weak axial current matrix elements. Our
results are in good agreement with experimental data.
