The results are obtained using data corresponding to an integrated luminosity of 3.0 fb−1 of proton-proton collisions recorded with the LHCb detector at centre-of-mass energies of 7 and 8 TeV. Together with constraints from B0 → J/ψ ρ0 , the results are used to constrain additional contributions due to penguin diagrams in the CP-violating phase φs, measured through B0 s decays to charmonium.41 p.application/pdfengcc-by (c) Badalov, A. et al., 2015https://creativecommons.org/licenses/by/4.0/HadronsGran Col·lisionador d'HadronsFísica de partículesExperimentsHadronsLarge Hadron Collider (France and Switzerland)Particle physicsExperimentsinfo:eu-repo/semantics/article6567802022-05-19info:eu-repo/semantics/openAccess
