Description
The T2K experiment is a long-baseline neutrino oscillation experiment and aims at measuring the CP-violation in neutrino oscillations. So far, T2K has shown results that disfavored the CP conservation with a confidence level of $2\sigma$. One of the largest systematic uncertainties in the current oscillation analysis is the uncertainty of electron neutrino cross-sections. To reduce the uncertainties and perform more precise measurements of neutrino oscillations, we are planning to upgrade our near detector complex ND280. SuperFGD (Super Fine-Grained Detector), one of the newly introduced detectors, will consist of about two million $1\ \mathrm{cm}^3$ scintillator cubes whose scintillation light will be read out from three directions through wave-length-shifting fibers and photon detectors. This novel structure of SuperFGD allows us to perform precise 3D tracking as well as calorimetry. This poster will report the EM shower reconstruction methods developed for SuperFGD and the results of electron neutrino selection.
