Search for a Structure in the Invariant Mass Spectrum with the ATLAS Experiment
A search for the narrow structure, X (5568), reported by the D0 Collaboration in the decay sequence X → B$$0\atop{s}$$π ± , B$$0\atop{s}$$ → J/ψΦ, is presented. The analysis is based on a data sample recorded with the ATLAS detector at the LHC corresponding to 4.9 fb-1 of pp collisions at 7 TeV and 19.5 fb-1 at 8 TeV. No significant signal was found. Upper limits on the number of signal events, with properties corresponding to those reported by D0, and on the X production rate relative to B$$0\atop{s}$$ mesons, ρX, were determined at 95% confidence level. The results are N (X) < 382 and ρX < 0.015 for B$$0\atop{s}$$ mesons with transverse momenta above 10 GeV, and N (X) < 356 and ρX < 0.016 for transverse momenta above 15 GeV. Finally, limits are also set for potential B$$0\atop{s}$$π ± resonances in the mass range 5550 to 5700 MeV.
