Abstract |
We study the B- -> D- D0 K0S reaction, recently analyzed by the LHCb Collaboration, where a clear signal for the exotic Tcs0(2870) state was reported. We call attention to a small peak in the D0K0S mass distribution that could correspond to a state of the same nature as the Tcs0(2870) (D*K<overline>* nature in the molecular picture), but with JP = 2+. In order to magnify the signal for the state, we calculate the moments of the angle-mass distribution, which are linear in the resonance signal, rather than quadratic for the angle integrated mass distribution. We find spectra for the moments with a strength far bigger than that for the angle integrated mass distribution, which should encourage the evaluation of these moments from the present measurements of the reaction. |
