Abstract
This thesis presents the branching fractions measurements of B0(s) -> J/ψK0Sh+h(')− (h(') = K,π) decays, corresponding to an integrated luminosity of 1.0 fb−1 of data recorded at a centre-of-mass energy of √s = 7TeV collected with the LHCb detector at CERN Large Hadron Collider (LHC) during 2011. The first observation of the
B0s -> J/ψK0SK±π-+ decay is reported, with a significance greater than 10 standard deviations. The B0 -> J/ψK0SK+K− decay is also observed for the first time. The branching fraction of B0 -> J/ψK0Sπ+π− is determined, to significantly better precision than previous measurements, using B0 -> J/ψK0S as a normalisation channel. Branching fractions and upper limits of the other B0(s) -> J/ψK0Sh+h(')− modes are determined relative to that of the B0 -> J/ψK0Sπ+π− decay. The findings of this thesis have been submitted to JHEP as detailed in Ref. [1].
