Systematic analysis of DJ(2580), D(2650), DJ*(2740), DJ(2760), DJ*(3000) and DJ*(3000) in the D meson family

In this work, we tentatively assign the charmed mesons D-J(2580), D-J*(2650), D-J(2740), D-J*(2760), D-J(3000) and D-J*(3000) observed by the LHCb collaboration according to their spin, parity and masses, then systematically study their strong decays to ground state charmed mesons plus pseudoscalar mesons with the P-3(0) decay model. Based on these studies, we assign the D-J*(2760) as the 1D5/23(-) state, the D-J*(3000) as the 1F5/22(+) or 1F7/24(+) state, the D-J(3000) as the 1F7/23(+) or 2P1/21(+) state in the D meson family. As a byproduct, we also study the strong decays of the states 2P1/20(+), 2P3/22(+), 3S1/21(-), 3S1/20(-) etc, which will be valuable in searching for the partners of these D mesons.
