| 英文摘要 | The strong and radiative decays of the low-lying s- and p-wave lambda(c(b)), sigma(c(b)), xi(c(b)), xi(c(b))', and omega(c(b)) baryons are systematically studied in a constituent quark model. we find that the radiative decay mode lambda(0)(b)gamma could be very useful for us to establish the missing neutral states sigma(0)(b) and sigma(b)*(0) our calculation shows that most of those missing lambda-mode p-wave singly heavy 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 sigma(c)(2800) resonance may be assigned to vertical bar sigma(2)(c)p(lambda)3/2(-)> with j(p) = 3/2(-) or vertical bar sigma(4)(c)p(lambda)5/2(-)> with j(p) = 5/2(-). in general, the excitations of vertical bar(2)p(lambda)3/2(-)> and vertical bar(4)p(lambda)5/2(-)> of the 6(f) multiplet have similar strong decay properties. in order to identify them, angular distributions of their decays in either strong decay modes or radiative transitions should be needed. |
