Abstract

The paper presents several recent ATLAS results on the analyses of B-meson decays into charmonium states. These include the measurements of B+ mass and the fractions of J/ψ mesons produced in b-hadron decays in pp collisions at \(\sqrt s\) = 13 TeV in the center of mass system. The measured partial widths and polarizations in B + c → J/ψD (*)+ s decays and CP-violation parameters in B 0 s → J/ψϕ decays in pp collisions at 7 and 8 TeV in the center of mass system are also presented.
