| Sumario: | <!--HTML--><p>The claim by the D0 collaboration of a tetraquark state, dubbed the X(5568), in the B<sub>s</sub><sup>0</sup> π<sup>+-</sup> invariant mass distribution is investigated with a data sample recorded with the LHCb detector corresponding to 3 fb<sup>-1</sup> of pp collision data at sqrt(s) =7 and 8 TeV. No signal is found and upper limits are set on the production rate of such a state.</p>
