Abstract
We provide results for the open-flavor strong decays of open-charm ($D$ and $D_{\rm s}$) and open-bottom ($B$, $B_{\rm s}$ and $B_{\rm c}$) mesons. The decays are calculated in a modified version of the $^3P_0$ pair-creation model, assuming harmonic oscillator wave functions. The spectra of open-charm and open-bottom mesons used in the calculations are computed within Godfrey and Isgur's relativized quark model. Quantum number assignments are also provided. Our results are compared with the existing experimental data.
Highlights
Since the discovery of the J=Ψ and Υ resonances in the1970s, heavy meson physics has been extensively studied and still is the subject of intensive theoretical and experimental research [10,11]
We focus on the 3P0 pair-creation model, in which the decays proceed via the production of qqpairs with vacuum quantum numbers, i.e., J PC 1⁄4 0þþ, somewhere in the hadronic medium [29]
We calculate the amplitudes by using the experimental values of the meson masses, extracted from the particle data group (PDG) [10]; otherwise, we use the
Summary
1970s, heavy meson physics (including the physics of charmonia [1,2], bottomonia [3,4], open-charm [5,6], and open-bottom [7,8,9] mesons) has been extensively studied and still is the subject of intensive theoretical and experimental research [10,11] Both the charmonium and bottomonium spectra have been enriched by the discovery of new particles [10,11]; the knowledge of open-charm and open-bottom mesons has improved substantially with the experimental observation of new resonances, including the D0 ð2400Þ [12,13], D1 ð2430Þ0. This has led to remarkable theoretical efforts to provide the experimentalists predictions for the spectrum, decay modes, and so on and attempts to make quark model assignments for new observed states
