Observation of B(s)(0) → J/ψ f1(1285) decays and measurement of the f1(1285) mixing angle.

Observation of B(s)(0) → J/ψ f1(1285) decays and measurement of the f1(1285) mixing angle.

Decays of B(s)(0) and B(0) mesons into J/ψ π+π-π+π- final states, produced in pp collisions at the LHC, are investigated using data corresponding to an integrated luminosity of 3 fb-1 collected with the LHCb detector. B(s)(0) → J/ψ f1(1285) decays are seen for the first time, and the branching fract...
