| Summary: | Title screen Measurements of B∗s2(5840)0Bs2∗(5840)0 and Bs1(5830)0Bs1(5830)0 mesons are performed using a data sample of proton-proton collisions corresponding to an integrated luminosity of Open image in new window, collected with the CMS detector at the LHC at a centre-of-mass energy of 8TeV8TeV. The analysis studies P-wave B0sBs0 meson decays into B(∗)+K−B(∗)+K− and B(∗)0K0SB(∗)0KS0, where the B+B+ and B0B0 mesons are identified using the decays B+→J/ψK+B+→J/ψK+ and B0→J/ψK∗(892)0B0→J/ψK∗(892)0. The masses of the P-wave B0sBs0 meson states are measured and the natural width of the B∗s2(5840)0Bs2∗(5840)0 state is determined. The first measurement of the mass difference between the charged and neutral B∗B∗ mesons is also presented. The B∗s2(5840)0Bs2∗(5840)0 decay to B0K0SB0KS0 is observed, together with a measurement of its branching fraction relative to the B∗s2(5840)0→B+K−Bs2∗(5840)0→B+K− decay |
