The OPERA (Oscillation Project with Emulsion tRacking Apparatus) experiment is a long baseline neutrino oscillation experiment that was designed to perform a conclusive test of the νμ → ντ oscillations hypothesis. The main aim of this experiment is a direct observation of τ leptons in ντ charged-current interactions. A good electromagnetic shower reconstruction is important for the τ detection in the τ → e decay channel. So far, 4 ντ candidates have been observed in the OPERA detector with a background of 0.23 events. Given the number of analyzed events and the low background, νμ → ντ oscillations are established with a significance of 4.2 σ. Reconstruction of e...
