 Title: Constraints on the unitarity triangle angle γ from Dalitz plot analysis of B0 →dK+π- decays Author: LHCb collaborationGascón Fora, DavidGraciani Díaz, RicardoGraugés Pous, EugeniMarin Benito, CPicatoste Olloqui, EduardoRives Molina, Vicente José Keywords: Gran Col·lisionador d'HadronsMesons (Física nuclear)AntimatèriaLarge Hadron Collider (France and Switzerland)Mesons (Nuclear physics)Antimatter Issue Date: 1-Jun-2016 Publisher: American Physical Society Abstract: The first study is presented of CP violation with an amplitude analysis of the Dalitz plot of $B^0 \to D K^+ \pi^-$ decays, with $D \to K^+ \pi^-$, $K^+ K^-$ and $\pi^+ \pi^-$. The analysis is based on a data sample corresponding to $3.0\,{\rm fb}^{-1}$ of $pp$ collisions collected with the LHCb detector. No significant CP violation effect is seen, and constraints are placed on the angle $\gamma$ of the unitarity triangle formed from elements of the Cabibbo-Kobayashi-Maskawa quark mixing matrix. Hadronic parameters associated with the $B^0 \to D K^*(892)^0$ decay are determined for the first time. These measurements can be used to improve the sensitivity to $\gamma$ of existing and future studies of the $B^0 \to D K^*(892)^0$ decay.
