Pionic and radiative transitions from T c s ¯ 0 + ( 2900 ) to D s 1 + ( 2460 ) as a probe of the structure of D s 1 + ( 2460 )
No full textAbstract In this work, we evaluated the widths of the pionic and radiative transitions from the T c s ¯ 0 + ( 2900 ) to the D s 1 + ( 2460 ) in the D s 1 + ( 2460 ) molecular frame and the D s 1 + ( 2460 ) charmed-strange meson frame. Our estimations demonstrate that the transition widths in the D s 1 + ( 2460 ) molecular frame are much larger than those in the the D s 1 + ( 2460 ) charmed-strange meson frame. Specifically, the ratio of the widths of Γ ( T c s ¯ 0 + ( 2900 ) → D s 1 + π 0 ) and Γ ( T c s ¯ 0 + ( 2900 ) → D + ( 0 ) K 0 ( + ) ) is estimated to be around 0.1 in the D s 1 + ( 2460 ) charmed-strange meson frame, whereas the lower limit of this ratio is 0.67 in the D s 1 + ( 2460 ) molecular frame. Thus, the aforementioned ratio could be employed as a tool for testing the nature of the D s 1 + ( 2460 )

Measurement of the Born cross sections for e+e−→D+sDs1(2460)−+c.c. and e+e−→D*+sDs1(2460)−+c.c.
No full textThe processes e(+)e(-) -> D-s(+) D-s1 (2460)(-) + c.c. and e(+) e(-) -> D-s*(+) D-s1 (2460)(-)+ c.c. are studied for the first time using data samples collected with the BESIII detector at the BEPCII collider. The Born cross sections of e(+)e(-) -> D-s(+) D-s1 (2460)(-) + c.c. at nine center-of-mass energies between 4.467 GeV and 4.600 GeV and those of e(+) e(-) -> D-s*(+) D-s1 (2460)(-)+ c.c. at root s = 4.590 GeV and 4.600 GeV are measured. No obvious charmonium or charmoniumlike structure is seen in the measured cross sections.For complete list of authors see http://dx.doi.org/10.1103/PhysRevD.101.112008</p

Properties of D - 2 * (2460) tensor meson and semileptonic transition of B -> D - 2 * (2460) l(v)over - bar
No full textWe employ QCD sum rules to calculate the leptonic decay constant of the D-2*(2460) tensor meson and the transition form factors of the semileptonic B -> D-2*(2460)l (v) over bar (l = tau,mu,e) decay channel. Using the fit functions of the form factors, we estimate the total decay widths and branching ratios of this transition at all lepton channels. The order of branching ratio indicates that this channel can be detected at LHC
Contribution of constituent quark model cs¯ states to the dynamics of the Ds0∗(2317) and Ds1(2460) resonances
No full textAbstract The masses of the Ds0∗(2317) and Ds1(2460) resonances lie below the DK and D∗K thresholds respectively, which contradicts the predictions of naive quark models and points out to non-negligible effects of the D(∗)K loops in the dynamics of the even-parity scalar ( Jπ=0+ ) and axial-vector ( Jπ=1+ ) cs¯ systems. Recent lattice QCD studies, incorporating the effects of the D(∗)K channels, analyzed these spin-parity sectors and correctly described the Ds0∗(2317)-Ds1(2460) mass splitting. Motivated by such works, we study the structure of the Ds0∗(2317) and Ds1(2460) resonances in the framework of an effective field theory consistent with heavy quark spin symmetry, and that incorporates the interplay between D(∗)K meson–meson degrees of freedom and bare P-wave cs¯ states predicted by constituent quark models. We extend the scheme to finite volumes and fit the strength of the coupling between both types of degrees of freedom to the available lattice levels, which we successfully describe. We finally estimate the size of the D(∗)K two-meson components in the Ds0∗(2317) and Ds1(2460) resonances, and we conclude that these states have a predominantly hadronic-molecular structure, and that it should not be tried to accommodate these mesons within cs¯ constituent quark model patterns
