CMS-BPH-16-003. CERN-EP-2018-224}, year = {2018}, abstract = {Measurements of $\mathrm{B}^*_\mathrm{s2}(5840)^0$ and $\mathrm{B}_\mathrm{s1}(5830)^0$ mesons are performed using a data sample of proton-proton collisions corresponding to an integrated luminosity of 19.6 fb$^{-1}$, collected with the CMS detector at the LHC at a centre-of-mass energy of 8 TeV. The analysis studies $P$-wave $\mathrm{B}^0_\mathrm{S}$ meson decays into $\mathrm{B}^{(*)+}\mathrm{K}^-$ and $\mathrm{B}^{(*)0}\mathrm{K}^0_\mathrm{S}$, where the $\mathrm{B}^+$ and $\mathrm{B}^0$ mesons are identified using the decays $\mathrm{B}^+\to\mathrm{J}/\psi\,\mathrm{K}^+$ and $\mathrm{B}^0\to\mathrm{J}/\psi\,\mathrm{K}^*(892)^0$. The masses of the $P$-wave $\mathrm{B}^0_\mathrm{S}$ meson states are measured and the natural width of the $\mathrm{B}^*_\mathrm{s2}(5840)^0$ state is determined. The first measurement of the mass difference between the charged and neutral $\mathrm{B}^*$ mesons is also presented. The $\mathrm{B}^*_\mathrm{s2}(5840)^0$ decay to $\mathrm{B}^0\mathrm{K}^0_\mathrm{S}$ is observed, together with a measurement of its branching fraction relative to the $\mathrm{B}^*_\mathrm{s2}(5840)^0\to\mathrm{B}^+\mathrm{K}^-$ decay.}, keywords = {p p: scattering (autogen) / meson: decay (autogen) / branching ratio (autogen) / mass difference (autogen) / CERN LHC Coll (autogen) / CMS (autogen)}, cin = {CMS}, cid = {I:(DE-H253)CMS-20120731}, pnm = {611 - Fundamental Particles and Forces (POF3-611)}, pid = {G:(DE-HGF)POF3-611}, experiment = {EXP:(DE-H253)LHC-Exp-CMS-20150101}, typ = {PUB:(DE-HGF)25 / PUB:(DE-HGF)29}, eprint = {1809.03578}, howpublished = {arXiv:1809.03578}, archivePrefix = {arXiv}, SLACcitation = {$\%\%CITATION$ = $arXiv:1809.03578;\%\%$}, doi = {10.3204/PUBDB-2018-03630}, url = {https://bib-pubdb1.desy.de/record/410482}, }
