Resumen
The Bs0π± invariant mass distribution is investigated in order to search for possible exotic meson states. The analysis is based on a data sample recorded with the LHCb detector corresponding to 3 fb-1 of pp collision data at s=7 and 8 TeV. No significant excess is found, and upper limits are set on the production rate of the claimed X(5568) state within the LHCb acceptance. Upper limits are also set as a function of the mass and width of a possible exotic meson decaying to the Bs0π± final state. The same limits also apply to a possible exotic meson decaying through the chain Bs∗0π±, Bs∗0→Bs0γ where the photon is excluded from the reconstructed decays.
