Search for Structure in the Bsπ Invariant Mass Spectrum

s p 1⁄4 7 and 8 TeV. No significant excess is found, and upper limits are set on the production rate of the claimed Xð5568Þ 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 Bsπ final state. The same limits also apply to a possible exotic meson decaying through the chain B 0 s π , B 0 s → Bsγ where the phot...
