The OPERA experiment was designed to study oscillations in appearance mode using the CERN to Gran Sasso high energy neutrino beam. From 2008 to 2012, 19505 CNGS neutrino interactions were recorded in the OPERA detector. At the present status of the analysis, 4 candidate events have been observed, establishing the oscillation mechanism in the atmospheric sector with a significance of 4.2 σ. The oscillation analysis will be presented in detail and the candidate events will be described. The final measurement of the atmospheric muon charge ratio in the TeV region will be also reported.

Final Results of the OPERA Experiment on nu(tau )Appearance In the CNGS Neutrino Beam Agafonova, N.; et. al. (American Physical Society (APS), 2018-05-22) The OPERA experiment was designed to study νμ→ντ oscillations in the appearance mode in the CERN to Gran Sasso Neutrino beam (CNGS). In this Letter, we report the final analysis of the full data sample collected between 2008 and 2012, corresponding to 17.97×1019 protons on target. Selection criteria looser than in previous analyses have produced ten ντ candidate events, thus reducing the statistical uncertainty in the measurement of the oscillation parameters and of ντ properties. A multivariate approach fo...
Observation of a first v(tau) candidate event in the OPERA experiment in the CNGS beam Agafonova, N.; et. al. (Elsevier BV, 2010-07-01) The OPERA neutrino detector in the underground Gran Sasso Laboratory (LNGS) has been designed to perform the first detection of neutrino oscillations in direct appearance mode through the study of the v(mu) -> v(tau) channel. The hybrid apparatus consists of an emulsion/lead target complemented by electronic detectors and it is placed in the high energy long-baseline CERN to LNGS beam (CNGS) 730 km away from the neutrino source. Runs with CNGS neutrinos were successfully carried out in 2008 and 2009. After ...
First events from the CNGS neutrino beam detected in the OPERA experiment Acquafredda, R; et. al. (IOP Publishing, 2006-12-5) The OPERA neutrino detector at the underground Gran Sasso Laboratory (LNGS) was designed to perform the first detection of neutrino oscillations in appearance mode, through the study of νµ → ντ oscillations. The apparatus consists of a lead/emulsion-film target complemented by electronic detectors. It is placed in the high-energy, long-baseline CERN to LNGS beam (CNGS) 730 km away from the neutrino source. In August 2006, a first run with CNGS neutrinos was successfully conducted. A first sample of ne...
New results on nu(mu) -> nu(tau) appearance with the OPERA experiment in the CNGS beam Agafonova, N.; et. al. (Springer Science and Business Media LLC, 2013-11-01) The OPERA neutrino experiment is designed to perform the first observation of neutrino oscillations in direct appearance mode in the nu(mu) -> nu(tau) channel, via the detection of the tau-leptons created in charged current nu(tau) interactions. The detector, located in the underground Gran Sasso Laboratory, consists of an emulsion/lead target with an average mass of about 1.2 kt, complemented by electronic detectors. It is exposed to the CERN Neutrinos to Gran Sasso beam, with a baseline of 730 km and a me...
Measurement of the neutrino velocity with the OPERA detector in the CNGS beam Adam, T.; et. al. (2012-10-01) The OPERA neutrino experiment at the underground Gran Sasso Laboratory has measured the velocity of neutrinos from the CERN CNGS beam over a baseline of about 730 km. The measurement is based on data taken by OPERA in the years 2009, 2010 and 2011. Dedicated upgrades of the CNGS timing system and of the OPERA detector, as well as a high precision geodesy campaign for the measurement of the neutrino baseline, allowed reaching comparable systematic and statistical accuracies. An arrival time of CNGS muon neu...
