- Аннотация: The present paper highlights the data analysis status of the OPERA experiment. The experiment was designed to perform the neutrino interactions analysis on event-by-event basis, and optimized to search for νμ→ντ oscillation in appearance mode, also allowing to perform a νe appearance search. We review the data simulation and the analysis chains implemented to search for ντ interactions. The main kinematical parameters sensitive to the neutrino flavor are discussed, the uncertainties of the event parameter estimation are reviewed, and the main sources of background for the νμ→ντ oscillation search are examined. The topologies of the two first ντ candidate events are presented. Finally, we review the status of the νe appearance search and present the constraints set by the OPERA experiment on the mixing angle θ13 and on the LSND/MiniBooNE anomaly.
