Discovery of Tacso (2900)0,+ + implies new charmed-strange pentaquark system

Inspired by the very recently discovered tetraquark states T-c (s) over bar0(alpha) (2900)(0, + +) from the LHCb Collaboration, we predict the existence of a new charmed-strange pentaquark system, c (s) over bar nnn, which is closely connected to c (s) over bar sn (n) over bar by exchanging (n) over bar into nn with n = u, d. Especially, it is suggested to experimentally search for the predicted new pentaquark system via the weak decays of B mesons or b baryons, with the support from the study of the mass spectrum and the decay properties. The predicted new pentaquark system must attract extensive attention from experimentalists and theorists when it constructs the particle zoo 2.0 in the near future.

Automated summary

This study predicts the existence of a new pentaquark system based on the discovery of tetraquark states. It suggests experimental search for the new system and emphasizes the importance of studying its mass spectrum and decay properties.
