Searching for tetraquark through weak decays of b-baryons

Abstract After the experimental observation of charged and neutral $$Z_c(3900)$$ Z c ( 3900 ) , it is prime importance to pursue searches for additional production modes these exotic states. In this work, we investigate possibility study through weak decays b-baryons at LHCb. Decay amplitudes various processes have been parametrized in terms SU(3) irreducible nonperturbative amplitudes. A number relations partial decay widths are deduced from results. The $$\Lambda _b^0\rightarrow \Lambda ^0 Z_c^0(3900)$$ ? b 0 ? $$\Xi _b^- \rightarrow \Sigma ^- Z_{c}^0(3900)$$ ? - ? _b^0 also calculated which some relevant could be estimated. results presented paper can tested experimentally hadron colliders future.
