Times Cited Count：70 Percentile：92.45(Astronomy & Astrophysics)We investigate the decays of the charmed baryons aiming at the systematic understanding of hadron internal structures based on the quark model by paying attention to heavy quark symmetry. We evaluate the decay widths from the one pion emission for the known excited states, 
, 
, 
, 
and 
, as well as for the ground states 
and 
. The calculated decay widths are in good agreement with the experimental data, and several important predictions for higher excited 
baryons are given. We also find that the axial-vector type coupling of the pion to the light quarks is essential, which is expected from chiral symmetry, to reproduce the decay widths especially of the low lying baryons. We emphasize the importance of the branching ratios of 
for the study of the nature of higher excited baryons.

Times Cited Count：3 Percentile：24.10(Physics, Nuclear)In this paper, we discuss reactions involving charmed baryons to explore their unique features. A well known phenomenon, the separation of the two internal motions of the 
and 
types of a three-quark system is revisited. First we discuss the mass spectrum of low-lying excitations as functions of the heavy quark mass, smoothly connecting the 
and heavy quark limits. The properties of these modes can be tested in the production and decay reactions of the baryons. For the productions, we consider a one step process which excites dominantly mode excitations. We find abundant production rates for some of excited states. For decays, we study pion emission process, which provides a clean tool to test the structure of heavy quark systems due to well controlled low energy dynamics of the pion and quark. Both productions and decays of the charmed baryons are the issues of the future experiments at J-PARC.
