Description
The T2K experiment is a long-baseline neutrino oscillation experiment and aims at measuring leptonic charge-parity (CP) violation in neutrino oscillations. So far, T2K has shown results that disfavor CP conservation with a significance of two standard deviations. One of the most significant systematic uncertainties is the uncertainty of the electron neutrino cross-section. To reduce the uncertainties and perform more precise measurements of neutrino oscillations, we plan to upgrade our magnetized near detector complex (ND280). SuperFGD (Super Fine-Grained Detector), one of the newly introduced detectors, will consist of about two million $1\ \mathrm{cm}^3$ optically-isolated scintillator cubes whose scintillation light will be read out from three orthogonal directions through wavelength shifting fibers and silicon photomultipliers. Such a novel structure allows us to perform isotropic 3D tracking and calorimetry with sub-ns time resolution. This poster will report the EM shower reconstruction methods developed for SuperFGD and the preliminary results based on Monte Carlo studies of electron neutrino selection.
