An analysis ofdecays is presented, whererepresents an admixture ofandmesons reconstructed in four separate final states:,,and. The data sample corresponds toof proton-proton collision, collected by the LHCb experiment. Measurements of several observables are performed, includingasymmetries. The most precise determination is presented of, the magnitude of the ratio of the amplitudes of the decaywith aor atransition, in amass region ofaround themass and for an absolute value of the cosine of thehelicity angle larger than 0.4.
