In this work,based on a non-relativistic constituent quark model,we have systematically studied the strong and radiative decays of the low-lying ?-mode 1D?wave single heavy baryons ?c(b),?c(b),?c(b),?c'(b)and ?c(b).For the strong decays of a heavy baryon,we only consider one pion and/or one kaon meson emitting processes.And for the radiative decays of a heavy baryon,we consider one photon emitting processes.Our calculation shows that(?)the missing ?-mode D-wave ?c(b),?b and ?b baryons have a relatively narrow decay width of less than 30 MeV,their dominant strong and radiative decay channels can be ideal for searching for their signals in future experiments.(?)The ?-mode 1D-wave excitations in the ?c(b)and ?c'(b)families appear to have a relatively broad width of larger than 50 MeV.These 1D-wave states have large decay rates into the 1P-wave heavy baryon states via the pionic or kaonic strong decay processes,which are worth to observing in future experiments.(?)Both ?c(2860)and ?c(3050)seem to favor the Jp=3/2+excitation |2D??3/2+>of 3F.while assignilg ?c(2880)and ?c(3080)as the JP=5/2+excitation |2D??5/2+>of 3F,one cannot well understand the measured partial width ratios from experimentsThere are few discussions of the radiative decay properties of the D-wave charmed and bottom baryons,and the strong decays of the D-wave bottom baryon-s.Thus,it is necessary to carry out a systematical study of the strong and radiative decays for the D-wave singly charmed and bottom baryons.In future experiments,we hope our research can provide valuable clues for finding the missing ?-mode D-wave ?c(b),?c(b),?c(b),?c'(b)and ?c(n)baryons. |
