Abstract
A model-dependent amplitude analysis of the decay B0 → D(KS0π+π−)K∗ 0 is performed using proton-proton collision data corresponding to an integrated luminosity of 3.0 fb−1, recorded at \( \sqrt{s}=7 \) and 8 TeV by the LHCb experiment. The CP violation observables x± and y±, sensitive to the CKM angle γ, are measured to be $$ \begin{array}{l}{x}_{-}=-0.15\pm 0.14\pm 0.03\pm 0.01,\hfill \\ {}{y}_{-}=0.25\pm 0.15\pm 0.06\pm 0.01,\hfill \\ {}{x}_{+}=0.05\pm 0.24\pm 0.04\pm 0.01,\hfill \\ {}{y}_{+}=-{0.65}_{-0.23}^{+0.24}\pm 0.08\pm 0.01,\hfill \end{array} $$ where the first uncertainties are statistical, the second systematic and the third arise from the uncertainty on the D → KS0π+π− amplitude model. These are the most precise measurements of these observables. They correspond to γ = (80− 22+ 21)° and \( {r}_{B^0}=0.39\pm 0.13 \), where \( {r}_{B^0} \) is the magnitude of the ratio of the suppressed and favoured B0 → DK+π− decay amplitudes, in a Kπ mass region of ±50 MeV around the K*(892)0 mass and for an absolute value of the cosine of the K*0 decay angle larger than 0.4.
