Meausrement of CP observables in B-->DK*+ decays using two and four body D final states
Journal of High Energy Physics Springer Verlag 2017:156 (2017) 1-27
Abstract:
Measurements of CP observables in B± → DK*± decays are presented, where D denotes a superposition of D0 and D0 meson states. Decays of the D meson to K- Π+, K-K+, Π-Π+, K- Π+ Π- Π+ and Π- Π+ Π- Π+ are used and the K*± meson is reconstructed in the K0 S± Π final state. This analysis uses a data sample of pp collisions collected with the LHCb experiment, corresponding to integrated luminosities of 1 fb-1, 2 fb-1 and 1.8 fb-1 at centre-of-mass energies p s = 7TeV, 8TeV and 13TeV, respectively. The sensitivity of the results to the CKM angle is discussed.Updated branching fraction measurements of B-(s)(0) -> K(S)(0)h(+)h'(-) decays

Measurement of B0, B0s, B+ and Λ0b production asymmetries in 7 and 8 TeV proton-proton collisions
Physics Letters B Elsevier 774 (2017) 139-158
Abstract:
The B0, Bs0, B+ and Λb0 hadron production asymmetries are measured using a data sample corresponding to an integrated luminosity of 3.0 fb^−1 , collected by the LHCb experiment in proton–proton collisions at centre-of-mass energies of 7 and 8 TeV. The measurements are performed as a function of transverse momentum and rapidity of the b hadrons within the LHCb detector acceptance. The overall production asymmetries, integrated over transverse momentum and rapidity, are also determined.Measurement of CP observables in B± → DK*± decays using two- and four-body D final states
