Strong decays of strange quarkonia

In this paper we evaluate strong decay amplitudes and partial widths of strange mesons (strangeonia and kaonia) in the 3 P 0 decay model. We give numerical results for all energetically allowed open-flavor two-body decay modes of all ns and ss strange mesons in the 1S, 2S, 3S, 1P, 2P, 1D and 1F multiplets, comprising strong decays of a total of 43 resonances into 525 two-body modes, with 891 numerically evaluated amplitudes. This set of resonances includes all strange qq states with allowed strong decays expected in the quark model up to ca. 2.2 GeV. We use standard nonrelativistic SHO quark model wavefunctions to evaluate these amplitudes, and quote numerical results for all amplitudes present in each decay mode. We also discuss the status of the associated experimental candidates, and note which states and decay modes would be especially interesting for future experimental study at hadronic, e + e − and photoproduction facilities. These results should also be useful in distinguishing conventional quark model mesons from exotica such as glueballs and hybrids through their strong decays. *

We developed a Friedrichs-model-like scheme in studying the hadron resonance phenomenology and present that the hadron resonances might be regarded as the Gamow states produced by a Hamiltonian in which the bare discrete state is described by the result of usual quark potential model and the interaction part is described by the quark pair creation model. In a one-parameter calculation, the X(3862), X(3872), and X(3930) state could be simultaneously produced with a quite good accuracy by coupling the three P-wave states, χc2(2P ), χc1(2P ), χc0(2P ) predicted in the Godfrey-Isgur model to the DD, DD * , D * D * continuum states. At the same time, we predict that the hc(2P ) state is at about 3902 MeV with a pole width of about 54 MeV. In this calculation, the X(3872) state has a large compositeness. This scheme may shed more light on the long-standing problem about the general discrepancy between the prediction of the quark model and the observed values, and it may also provide reference for future search for the hadron resonance state.PACS numbers: 12.39. Jh, 13.25.Gv, 13.75.Lb, 11.55.Fv As regards the charmonium spectrum above the openflavor thresholds, general discrepancies between the predicted masses in the quark potential model and the observed values have been highlighted for several years. Typically, among the P-wave n 2s+1 L J = 2 3 P 2 , 2 3 P 1 , 2 3 P 0 , and 2 1 P 1 states, the X(3930), discovered by the Belle Collaboration [1], is now assigned to χ c2 (2P ) charmonium state though its mass is about 50 MeV lower than the prediction in the quark potential model [2][3][4]. The properties of the other P-wave states have not been firmly determined yet. The X(3872) was first observed in the B ± → K ± J/ψπ + π − by the Belle Collaboration in 2003 [5]. Although its quantum number is 1 ++ , the same as the χ c1 (2P ), the pure charmonium interpretation was soon given up for the difficulties in explaining its decays. The pure molecular state explanation of X(3872) also encounters difficulties in understanding its radiative decays. So its nature remains to be obscure up to now. As for the χ c0 (2P ) state, the X(3915) is assigned to it several years ago, but this assignment is questioned for the mass splitting between χ c2 (2P ) and χ c0 (2P ), and its dominant decay mode [6,7]. In Ref.[8], analyses of the angular distribution of X(3915) to the final leptonic and pionic states also support the possibility of being a 2 ++ state, which means that it might be the same tensor state as the X(3930). Very recently, the Belle Collaboration announced a new result about the signal of X(3862) which could be a candidate for the χ c0 (2P ) [9]. The 2 1 P 1 state has not been discovered yet. These puzzles have been discussed exhaustively in the literatures (see refs. [10][11][12] for example), but a consistent description is still missing.In this paper, we adopt the idea of Gamow states and the solvable extended Friedrichs model developed recently [13][14][15], usually discussed in the pure mathematical physics literatur...

“…After the QPC model [17] was proposed, this model was further developed by the Orsay group of Le Yaouanc et al [23][24][25][26][27]. Later, this model was widely applied to study the OZIallowed strong decay of hadrons [28][29][30][31][32][33][34][35][36][37][38][39][40][41][42][43][44][45][46].…”

In this work, we study all the observed a 2 states and group them into the a 2 meson family, where their total and two-body Okubo-Zweig-Iizuka allowed strong decay partial widths are calculated via the quark pair creation model. Taking into account the present experimental data, we further give the corresponding phenomenological analysis, which is valuable to test whether each a 2 state can be assigned into the a 2 meson family. What is more important is that the prediction of their decay behaviors will be helpful for future experimental study of the a 2 states.
