Electron Neutrino Identification in the MINOS Detectors

The MINOS experiment has the potential to further constrain or make the first measurement of the neutrino mixing angle $\theta_{13}$. It is very important to understand the electromagnetic and hadronic showers in the MINOS detectors. Several discriminating methods and techniques are developed to separate the $\nu_{e}$ signals from a huge amount of backgrounds. The details of these techniques are discussed.
