Abstract	Many P-wave mixing heavy-light 1(+) states have not yet been discovered by experiment, while others have been discovered but without width information, or with large uncertainties on the widths. In this paper, the strong decays of the P-wave mixing heavy-light 1(+) states D-0, D-+/-, D-s(+/-), B-0, B-+/- and B-s are studied by the improved BetheSalpeter (B-S) method with two conditions of mixing angle theta: one is theta=35.3 degrees; the other is considering a correction to the mixing angle theta=35.3 degrees+theta(1). Valuable predictions for the strong decay widths are obtained: Gamma(D '(0)(1))=232, MeV, Gamma(D-1(0))=21.5 MeV, Gamma(D '(+/-)(1))=232 MeV, Gamma(D-1(+/-))=21.5 MeV, Gamma(D '(+/-)(s1))=0.0101 MeV, Gamma(D-s1(+/-))=0.950 MeV, Gamma(B '(+/-)(1))=263 MeV, Gamma(B-1(+/-)) =16.8 MeV, Gamma(B '(s1)) =0.01987 MeV and Gamma(B-s1) =0.412 MeV. It is found that the decay widths of D-s1(+/-) and B-s1 are very sensitive to the mixing angle. The results will provide theoretical assistance to future experiments.
