The analysis is made possible by a dedicated data set of proton-proton collisions at recorded in 2018, by the CMS experiment at the LHC, using a special high-rate data stream designed for collecting about 10 billion unbiased b hadron decays. The ratio of the branching fractions to is determined from the measured double ratio of these decays to the respective branching fractions of the with and decays, which allow for significant cancellation of systematic uncertainties. The ratio is measured in the range , where q is the invariant mass of the lepton pair, and is found to be , in agreement with the standard model expectation . This measurement is limited by the statistical precision of the electron channel. The integrated branching fraction in the same q$^{2}$ range, , is consistent with the present world-average value and has a comparable precision.}, keywords = {p p: colliding beams (INSPIRE) / lepton: flavor: universality (INSPIRE) / p p: scattering (INSPIRE) / B: semileptonic decay (INSPIRE) / muon: pair production (INSPIRE) / K (INSPIRE) / B: branching ratio (INSPIRE) / flavor: universality (INSPIRE) / lepton: mass (INSPIRE) / lepton: flavor (INSPIRE) / branching ratio: ratio (INSPIRE) / branching ratio: ratio: measured (INSPIRE) / hadron: decay (INSPIRE) / electron: pair production (INSPIRE) / mass spectrum: (muon+ muon-) (INSPIRE) / mass spectrum: (electron positron) (INSPIRE) / CERN LHC Coll (INSPIRE) / statistical (INSPIRE) / CMS (INSPIRE) / experimental results (INSPIRE) / B+ --> K+ muon+ muon- (INSPIRE) / B- --> K- muon+ muon- (INSPIRE) / B+ --> K+ electron positron (INSPIRE) / B- --> K- electron positron (INSPIRE) / 13000 GeV-cms (INSPIRE) / CMS (autogen) / B physics (autogen) / lepton flavor universality (autogen) / B meson (autogen) / b to sll transitions (autogen)}, cin = {CMS}, ddc = {530}, cid = {I:(DE-H253)CMS-20120731}, pnm = {611 - Fundamental Particles and Forces (POF4-611) / DFG project G:(GEPRIS)390833306 - EXC 2121: Quantum Universe (390833306) / GRK 2497 - GRK 2497: Physik der schwersten Teilchen am Large Hadron Collider (400140256) / HIDSS-0002 - DASHH: Data Science in Hamburg - Helmholtz Graduate School for the Structure of Matter $(2019_IVF-HIDSS-0002)$}, pid = {G:(DE-HGF)POF4-611 / G:(GEPRIS)390833306 / G:(GEPRIS)400140256 / $G:(DE-HGF)2019_IVF-HIDSS-0002$}, experiment = {EXP:(DE-H253)LHC-Exp-CMS-20150101}, typ = {PUB:(DE-HGF)16}, eprint = {2401.07090}, howpublished = {arXiv:2401.07090}, archivePrefix = {arXiv}, SLACcitation = {$\%\%CITATION$ = $arXiv:2401.07090;\%\%$}, pubmed = {pmid:38957892}, UT = {WOS:001287343200001}, doi = {10.1088/1361-6633/ad4e65}, url = {https://bib-pubdb1.desy.de/record/612359}, }
