Systematic analysis of D_J(2580), D_J~*(2650), D_J(2740), D_J~*(2760),D_J(3000) and D_J~*(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 the3P0 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.
