“…So far, the OPERA experiment observed four ν τ CC interaction candidates, consistent with 2.3 events expected in the standard three neutrino oscillations framework at the so-called atmospheric scale (∆m 2 32 ∼ 2.4 × 10 −3 eV 2 [4]) with close-to-maximal mixing. This result represents the first direct observation of ν µ → ν τ oscillations in appearance mode [5] and it adds to the consistency of the standard three neutrino oscillations framework. Anyway, several experimental anomalies exist in neutrino oscillation data that cannot be accommodated in the standard three neutrino oscillations framework (the Gallium [6,7] and nuclear reactor anomalies [8], the LSND [10] and MiniBooNE [9] results) that may hint to the existence of sterile neutrino(s) with a new squared mass difference (∆m 2 41 ) of the order of 1 eV 2 .…”

“…where Φ ν µ is the CNGS muon neutrino flux [15], K is a normalization constant which includes the proton on target (pot) and the detector mass averaged on the pot, while N bkg = 0.23 is the expected number of background events [5]. The cross-section of ν τ CC interaction on 208 Pb (σ ν τ ) is evaluated using GENIE [16].…”

The OPERA experiment observed ν µ → ν τ oscillations in the atmospheric sector. To this purpose the hybrid OPERA detector was exposed to the CERN Neutrinos to Gran Sasso beam from 2008 to 2012, at a distance of 730 km from the neutrino source. Charged-current interactions of ν τ were searched for through the identification of τ lepton decay topologies. The four observed ν τ interactions are consistent with the expected number of events in the standard three neutrino framework. In this work, we interpret the results in terms of the 3 + 1 sterile neutrino model using the GLoBES software. This analysis allows to constrain the effective mixing of the sterile and the new squared mass difference.

“…It is designed to distinguish ν τ and ν τ by performing the electric charge measurement of the τ decay products. So far only DONUT [9] and OPERA [10] experiments succeeded in detecting a few ν τ interactions. The ECC structure is well suited for the measurement of charged particles momenta [11] and for electron identification [12], as largely exploited with the OPERA experiment.…”
