“…A recent determination provided by BABAR collaboration [40], quoted in Table II, is larger than our result, possibly signalling a mixing with the other axial-vector state D 0 s1 ð2460Þ [41]. In the case of beauty, in the T doublet only the width of the B Ã0 2 meson has been measured, with the result h 0 ¼ 0:36 AE 0:09.…”

All the available experimental information on open charm and beauty mesons is used to classify the observed states in heavy quark doublets. The masses of some of the still unobserved states are predicted, in particular in the beauty sector. Adopting an effective Lagrangian approach based on the heavy quark and chiral symmetry, individual decay rates and ratios of branching fractions are computed, with results useful to assign the quantum numbers to recently observed charmed states which still need to be properly classified. Implications and predictions for the corresponding beauty mesons are provided. The experimental results are already copious, and are expected to grow up thanks to the experiments at the LHC and to the future high-luminosity flavour and $p-\bar p$ facilities.Comment: RevTex, 15 pages, 1 figure.

“…It would be interesting to also consider coupling to the D * K in d-wave since in the heavy quark limit this mode is dominant for the j P = 3 2 + doublet of which the D s1 (2536) is part, with the s-wave channel absent [13] (the opposite holds for the j P = 1 2 + doublet which contains the D s1 (2460)). Experimentally, the s-wave mode dominates and its contribution to the total width is 0.72(5)(1) [96]. At present, our best estimate of the physical D s1 (2536) energy is again provided by the m π = 150 MeV, L = 64a ensemble.…”

We perform a high statistics study of the J P = 0 + and 1 + charmed-strange mesons, D * s0 (2317) and Ds1(2460), respectively. The effects of the nearby DK and D * K thresholds are taken into account by employing the corresponding four quark operators. Six ensembles with N f = 2 nonperturbatively O(a) improved clover Wilson sea quarks at a = 0.07 fm are employed, covering different spatial volumes and pion masses: linear lattice extents L/a = 24, 32, 40, 64, equivalent to 1.7 fm to 4.5 fm, are realised for mπ = 290 MeV and L/a = 48, 64 or 3.4 fm and 4.5 fm for an almost physical pion mass of 150 MeV. Through a phase shift analysis and the effective range approximation we determine the scattering lengths, couplings to the thresholds and the infinite volume masses. Differences relative to the experimental values are observed for these masses, however, this is likely to be due to discretisation effects as spin-averaged quantities and splittings are reasonably compatible with experiment. We also compute the weak decay constants of the scalar and axialvector and find f

“…The BaBar Collaboration reported this state in the D + s π + π − invariant mass spectrum [6]. The Belle Collaboration observed D s1 (2536) → D + π − K + decay mode [35], where the ratio B(D + s1 (2536) → D + π − K + )/B(D + s1 (2536) → D * + K + ) = (3.27 ± 0.18 ± 0.37)% was obtained. In addition, the measurement of the angular distribution of the D s1 (2536) + → D * + K 0 s indicates that D s1 (2536) + → D * + K 0 s dominantly occurs via S -wave with Γ(D s1 (2536) + → D * + K 0 s ) S −wave /Γ(D s1 (2536) + → D * + K 0 s ) total = (0.72 ± 0.05 ± 0.01).…”

Charmed-strange mesons revisited: Mass spectra and strong decays

Inspired by the present experimental status of charmed-strange mesons, we perform a systematic study of the charmed-strange meson family in which we calculate the mass spectra of the charmed-strange meson family by taking a screening effect into account in the Godfrey-Isgur model and investigate the corresponding strong decays via the quark pair creation model. These phenomenological analyses of charmed-strange mesons not only shed light on the features of the observed charmed-strange states, but also provide important information on future experimental search for the missing higher radial and orbital excitations in the charmed-strange meson family, which will be a valuable task in LHCb, the forthcoming Belle H, and PANDA.
