Issue Date: | May-2018 | Publisher: | American Physical Society | Source: | ATLAS collaboration. (2018). Search for a Structure in the B s 0 ?±Invariant Mass Spectrum with the ATLAS Experiment. Physical review letters, 120(20), 202007. | Abstract: | A search for the narrow structure, X(5568), reported by the D0 Collaboration in the decay sequence X?Bs0?±, Bs0?J/??, 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 Bs0 mesons, ?X, were determined at 95% confidence level. The results are N(X)<382 and ?X<0.015 for Bs0 mesons with transverse momenta above 10 GeV, and N(X)<356 and ?X<0.016 for transverse momenta above 15 GeV. Limits are also set for potential Bs0?± resonances in the mass range 5550 to 5700 MeV. © 2018 CERN. | URI: | https://journals.aps.org/prl/abstract/10.1103/PhysRevLett.120.202007 https://hdl.handle.net/20.500.11851/3635 |
