Observation of the B± meson in the decay B± → J/ψ (μ+μ−) K± in ATLAS

The production of B± mesons is observed in ATLAS through their decay to J/ψ (μ+μ−)K±, using 3.4 pb−1 of 7 TeV LHC collisions. A total of 283 ± 22(stat.) signal decays are observed after subtracting the background, with a fitted mass of 5283.2 ± 2.5(stat.) MeV. Within the statistical uncertainty, the...

description The production of B± mesons is observed in ATLAS through their decay to J/ψ (μ+μ−)K±, using 3.4 pb−1 of 7 TeV LHC collisions. A total of 283 ± 22(stat.) signal decays are observed after subtracting the background, with a fitted mass of 5283.2 ± 2.5(stat.) MeV. Within the statistical uncertainty, the fitted mass is consistent with the world average value.
