Inspired by the very recently discovered tetraquark states $T_{c\bar s 0}^a(2900)^{0,++}$ from LHCb Collaboration, we predict existence of a new charmed-strange pentaquark system, $c\bar nnn$, which is closely connected to n\bar n$ exchanging $\bar into $nn$ with $n=u,d$. Especially, it suggested experimentally search for predicted system via weak decays $B$ mesons or $b$-baryons, support study...

Abstract We report a search for heavier partner of the recently observed state, denoted as Z_{cs}^{\prime -} , in process e^{+} e^{-}\rightarrow K^{+}D_{s}^{*-}D^{* 0}+c.c. based on e^+e^- collision data collected at center-of-mass energies \sqrt{s}=4.661 4.682 and 4.699 GeV with BESIII detector. The is interest it expected to be candidate hidden-charm open-strang...
