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

  • In this work, we tentatively assign the charmed mesons DJ(2580), DJ*(2650), DJ(2740), DJ*(2760), DJ(3000) and DJ*(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 3P0 decay model. Based on these studies, we assign the DJ*(2760) as the 1D(5/2)3- state, the DJ*(3000) as the 1F(5/2)2+ or 1F(7/2)4+ state, the DJ(3000) as the 1F(7/2)3+ or 2P(1/2)1+ state in the D meson family. As a byproduct, we also study the strong decays of the states 2P(1/2)0+, 2P(3/2)2+, 3S(1/2)1-, 3S(1/2)0- etc, which will be valuable in searching for the partners of these D mesons.

Abstract: In this work, we tentatively assign the charmed mesons DJ(2580), DJ*(2650), DJ(2740), DJ*(2760), DJ(3000) and DJ*(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 3P0 decay model. Based on these studies, we assign the DJ*(2760) as the 1D(5/2)3- state, the DJ*(3000) as the 1F(5/2)2+ or 1F(7/2)4+ state, the DJ(3000) as the 1F(7/2)3+ or 2P(1/2)1+ state in the D meson family. As a byproduct, we also study the strong decays of the states 2P(1/2)0+, 2P(3/2)2+, 3S(1/2)1-, 3S(1/2)0- etc, which will be valuable in searching for the partners of these D mesons.
