Measurement of B0s meson production in pp and PbPb collisions at √sNN=5.02 TeV
(2019) [Artículo de periódico]The production cross sections of BOs mesons and charge conjugates are measured in proton-proton (pp) and PbPb collisions via the exclusive decay channel B0s→J/ψφ→μ+μ−K+K at a center-of-mass energy of 5.02 TeV per nucleon ... -
Measurement of the B0 s → μ+μ− decay properties and search for the B0 → μ+μ− decay in proton-proton collisions at √s = 13 TeV
(2023) [Artículo de periódico]Measurements are presented of the B0 s → μ+μ− branching fraction and effective lifetime, as well as results of a search for the B0 → μ+μ− decay in proton-proton collisions at √s = 13 TeV at the LHC. The analysis is based ... -
Observation of B0 s mesons and measurement of the B0 s /B+ yield ratio in PbPb collisions at √snn = 5.02 TeV
(2022) [Artículo de periódico]The B0 s and B+ production yields are measured in PbPb collisions at a center-of-mass energy per nucleon pair of 5.02 TeV. The data sample, collected with the CMS detector at the LHC, corresponds to an integrated luminosity ... -

Studies of B*s2(5840)0 and Bs1(5830)0 mesons including the observation of the B*s2(5840)0 → B0K0S decay in proton-proton collisions at √s = 8 TeV
(2018) [Artículo de periódico]Measurements of B*s2(5840)0 and Bs1(5830)0 mesons are performed using a data sample of protonproton collisions corresponding to an integrated luminosity of 19.6 fb−1, collected with the CMS detector at the LHC at a ...
