The OPERA experiment has reported the detection of five $\nu_{\tau}$ candidates in the CNGS $\nu_{\mu}$ beam, allowing to reject the background-only hypothesis at the 5.1$\sigma$ level. Besides these events, on May 23$^{rd}$ 2011, OPERA…
On 2010 MINOS experiment was showing an hint of possible different mass splitting and mixing angles for neutrinos and anti-neutrinos, suggesting a charge-parity-time (CPT) violation in the lepton sector; last year 2012 a second result from…
