摘要:	We calculate the two-body strong decays of the orbitally excited scalar mesons D-0* (2400) and D-J* (3000) by using the relativistic Bethe-Salpeter (BS) method. D-J* (3000) was observed recently by the LHCb Collaboration, the quantum number of which has not been determined yet. In this paper, we assume that it is the 0(+) (2P) state and obtain the transition amplitude by using the PCAC relation, low-energy theorem and effective Lagrangian method. For the 1P state, the total widths of D-0* (2400) 0 and D-0* (2400)(+) are 226 and 246 MeV, respectively. With the assumption of 0(+) (2P) state, the widths of D-J* (3000) 0 and D-J* (3000)(+) are both about 131 MeV, which is close to the present experimental data. Therefore, D-J* (3000) is a strong candidate for the 2(3)P(0) state.
