Search for structure in the $B_s^0\pi^\pm$ invariant mass spectrum
The claim by the D0 collaboration of the observation of a tetraquark state, dubbed the $X(5568)$, in the $B_s^0\pi^\pm$ invariant mass distribution is investigated. The analysis is based on a data sample recorded with the LHCb detector corresponding to $3 \ {\rm fb}^{-1}$ of $pp$ collision data at $...
