Strong Decays of Charm Mesons D * ₁ (2680), D * ₃ (2760), D * ₂ (3000)

Abstract

In this article, we assign the higher charm mesons D * 1 (2680), D * 3 (2760) and D * 2 (3000) to be the 2S 1 − , 1D 3 − and 1F 2 + states, respectively, and study the two-body strong decays to the ground state charm mesons and light pseudoscalar mesons with the heavy meson effective theory. We obtain the ratios among the strong decays, which can be confronted to the experimental data in the future and shed light on the nature of those higher charm mesons.

Open-flavor strong decays of open-charm and open-bottom mesons in the P03 model

“…[27] [10]. In the D Ã s3 ð2860Þ case, we also show predictions extracted by using the relativized QM mass for the decaying meson because I) There is a large difference between experimental and calculated masses and II) the experimental data are not very reliable as, at the moment, the state is excluded from the PDG summary table [10].…”

“…Our 3 P0 model results are compared to those of Heavy Meson Effective Theories (HMET) of Refs. [23,27], Lagrangian approaches with heavy quark and chiral symmetries (HQCS) of Refs. [24], and the experimental data [10,16,[61][62][63]65].…”

“…The spin-orbit potential [50], [23,27], Lagrangian approaches with heavy quark and chiral symmetries (HQCS) of Refs. [24], and the experimental data [10,16,[61][62][63][64].…”

“…The possibility of providing a theoretical description of (open-and hidden-flavor) strong decays relies mainly on phenomenological models, because the operators that describe the strong transitions between hadrons, arising from nonperturbative QCD, are essentially unknown. In the open-flavor case, they include, among other things, "hadrodynamic" models, pair-creation models, elementary meson emission models, heavy meson effective theories, and Lagrangian approaches with heavy-quark and chiral symmetries [19][20][21][22][23][24][25][26][27]. For a review, see Ref.…”

Mass spectroscopy and strong decays of excited open charm $${D}_{J}$$ mesons using relativistic Dirac formalism

“…However, the L HCb collaboration assigned J P = 2 + for D * 2 (3000) while D * J (3000) has natural parity. The mass energy difference between D * 2 (3000) and D * J (3000) is 206 MeV which suggests that they both are different states [51]. The mass range 3214 ± 29 ± 33 MeV likely to fall in the mass spectra of 2P, 3P and 1F multiplets.…”
