Decays of the fully open flavor state Tc0s-0 in a D?K? molecule scenario

Inspired by the recent observations of T0= thorn thorn cs over bar 0 in the processes B0 - over bar D0D thorn sp- and B thorn -D-D thorn s p thorn by LHCb Collaboration, we investigate the decay properties of the T0cs over bar 0 in a D?K? molecule scenario, and the widths of T0cs over bar 0 -D0K0, D thorn s p-, D? thorn s ?-, Do0 thorn thorn s1 p-, and D?0oDp thorn 0 are estimated. Our estimations indicate that the width of T0cs over bar 0 -D thorn s p- is sizable to be observed and the dominant decay mode of T0cs over bar 0 is D0K0. Considering the isospin symmetry, we proposed to search Tcs over bar 0o2900 thorn thorn thorn in the D thorn K thorn invariant mass distributions of the process B thorn -D thorn D-K thorn , where some preliminary experimental hints have been observed by LHCb Collaboration.
