Özet

Measurements of Bs2∗(5840)0 and B _{s 1}(5830) ⁰ mesons are performed using a data sample of proton-proton collisions corresponding to an integrated luminosity of [InlineEquation not available: see fulltext.], collected with the CMS detector at the LHC at a centre-of-mass energy of 8TeV. The analysis studies P-wave Bs0 meson decays into B ^{(∗) +}K ^- and B(∗)0KS0, where the B ⁺ and B ⁰ mesons are identified using the decays B ⁺→ J / ψK ⁺ and B ⁰→ J / ψK ^∗(892) ⁰. The masses of the P-wave Bs0 meson states are measured and the natural width of the Bs2∗(5840)0 state is determined. The first measurement of the mass difference between the charged and neutral B ^∗ mesons is also presented. The Bs2∗(5840)0 decay to B0KS0 is observed, together with a measurement of its branching fraction relative to the Bs2∗(5840)0→B+K- decay.
