Abstract
A search for the narrow structure, Xð5568Þ, reported by the D0 Collaboration in the decay sequence X → B0 sπ, B0 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 B0 s mesons, ρX, were determined at 95% confidence level. The results are NðXÞ < 382 and ρX < 0.015 for B0 s mesons with transverse momenta above 10 GeV, and NðXÞ < 356 and ρX < 0.016 for transverse momenta above 15 GeV. Limits are also set for potential B0 sπ resonances in the mass range 5550 to 5700 MeV.
