英文摘要The strong and radiative decay properties of the low-lying Omega(c) states are studied in a constituent quark model. We find that the newly observed Omega(c) states by the LHCb Collaboration can fit well in the decay patterns. Thus, their spin parity can possibly be assigned as the following: (i) Omega(c) (3000) has J(P) = 1/2(-) and corresponds to the narrow 1P mixed state vertical bar 1(2)P(lambda)1-/2 >(1); its partner vertical bar 1(2)P(lambda)1-/2 >(2) should be a broad state with a width of similar to 100 MeV. (ii) Omega(c) (3050) and Omega(c) (3066) can be assigned to be two J(P) = 3/2(-) states, vertical bar 1(4)P(lambda)3-/2 > and vertical bar 1(2)P(lambda)3-/2 >, respectively. (iii) Omega(c) (3090) can be assigned as the vertical bar 1(4)P(lambda)5-/2 > state with J(P) = 5/2(-). (iv) Omega(c) (3119) might correspond to one of the two 2S states of the first radial excitations, i.e., vertical bar 2(2)S(lambda lambda)1+/2 > or vertical bar 2(4)S(lambda lambda)3+/2 >.
