The D s0(2590)+ as the dressed c s ¯ ( 2 1 S 0 ) meson in a coupled-channels calculation
The recent discovery of the D s 0 ( 2590 ) + meson by the LHCb Collaboration has stimulated the analysis of meson-meson channels effects in the two-body quark-antiquark meson spectrum. This resonance, assigned to the radial excitation of the pseudoscalar D s + meson, has a mass much lower than the p...

520 | |a The recent discovery of the D s 0 ( 2590 ) + meson by the LHCb Collaboration has stimulated the analysis of meson-meson channels effects in the two-body quark-antiquark meson spectrum. This resonance, assigned to the radial excitation of the pseudoscalar D s + meson, has a mass much lower than the predictions of naive quark models, which could indicate a non-negligible D ( ⁎ ) K ( ⁎ ) coupling which reduces its mass. Based on the importance of nearby meson-meson thresholds in the dynamics of P-wave D s mesons such as the D s 0 ⁎ ( 2317 ) + and D s 1 ( 2460 ) + , in this work we perform a coupled-channels calculation including the D ( ⁎ ) K ( ⁎ ) , D s ( ⁎ ) ω and D s ⁎ η channels, and study the impact of incorporating those channels in the mass of the bare c s ¯ . The coupling between two and four-quark sectors is done by means of the P 0 3 mechanism, with all the parameters constrained from previous studies of the heavy meson spectroscopy. The masses, widths and production line shapes of the resulting state are analyzed. | ||

The recent discovery of the D s 0 ( 2590 ) + meson by the LHCb Collaboration has stimulated the analysis of meson-meson channels effects in the two-body quark-antiquark meson spectrum. This resonance, assigned to the radial excitation of the pseudoscalar D s + meson, has a mass much lower than the predictions of naive quark models, which could indicate a non-negligible D ( ⁎ ) K ( ⁎ ) coupling which reduces its mass. Based on the importance of nearby meson-meson thresholds in the dynamics of P-wave D s mesons such as the D s 0 ⁎ ( 2317 ) + and D s 1 ( 2460 ) + , in this work we perform a coupled-channels calculation including the D ( ⁎ ) K ( ⁎ ) , D s ( ⁎ ) ω and D s ⁎ η channels, and study the impact of incorporating those channels in the mass of the bare c s ¯ . The coupling between two and four-quark sectors is done by means of the P 0 3 mechanism, with all the parameters constrained from previous studies of the heavy meson spectroscopy. The masses, widths and production line shapes of the resulting state are analyzed. |
