Search for a structure in the B0sπ± 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→B0sπ±, B0s→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 signif...

Description
Summary:A search for the narrow structure, X(5568), reported by the D0 Collaboration in the decay sequence X→B0sπ±, B0s→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 B0s mesons, ρX, were determined at 95% confidence level. The results are N(X)<382 and ρX<0.015 for B0s mesons with transverse momenta above 10 GeV, and N(X)<356 and ρX<0.016 for transverse momenta above 15 GeV. Limits are also set for potential B0sπ± resonances in the mass range 5550 to 5700 MeV.
