Analysis of Muon Neutrino Interactions with an Increased Phase Space Coverage in the Near Detector of the T2K Experiment

Using of data from the ND280 near detector plays a key role in reducing systematic errors and increasing the accuracy of neutrino oscillation analysis in the T2K long-baseline accelerator experiment. A significant limitation is the relatively small phase space available for measurements in ND280. This work is devoted to the use of new methods for reconstructing and selecting neutrino reaction products, which allows for a significant increase of the kinematic range of analysis.
