Search for possible tetraquark state X(5568) with LHCb data

 

The claim by the D0 collaboration of a tetraquark state, dubbed the X(5568), in the Bs0 ПЂ+- invariant mass distribution is investigated with a data sample recorded with the LHCb detector corresponding to 3 fb-1 of pp collision data at sqrt(s) =7 and 8 TeV.
