The OPERA experiment was designed to discover the v(tau) appearance in a v(mu) beam, due to neutrino oscillations. The detector, located in the underground Gran Sasso Laboratory, consisted of a nuclear photographic emulsion/lead target with a mass of about 1.25 kt, complemented by electronic detectors. It was exposed from 2008 to 2012 to the CNGS beam: an almost pure v(mu) beam with a baseline of 730 km, collecting a total of 1.8 center dot 10(20) protons on target. The OPERA Collaboration eventually assessed the discovery of v(mu)-> v(tau) oscillations with a statistical significance of 6.1 sigma by observing ten v(tau) CC interaction candidates. These events have been published on the Open Data Portal at CERN. This paper provides a ydetailed description of the v(tau) data sample to make it usable by the whole community.

OPERA neutrino oscillation results
Güler, Ali Murat (2012-11-01)
The OPERA experiment was designed to perform the first detection of v(mu) -> v(T) neutrino oscillations in a direct appearance mode. We present the analysis results of the 2008-2009 statistics corresponding to 4.88 x 10 19 p.o.t. In this sample, one v(T) candidate event has been observed in the T -> h channel. The statistical significance of this observation is estimated to be 95%.
Discovery of tau Neutrino Appearance in the CNGS Neutrino Beam with the OPERA Experiment
Agafonova, N.; et. al. (2015-09-01)
The OPERA experiment was designed to search for nu(mu) -> nu(tau) oscillations in appearance mode, i.e., by detecting the tau leptons produced in charged current nu(tau) interactions. The experiment took data from 2008 to 2012 in the CERN Neutrinos to Gran Sasso beam. The observation of the nu(mu) -> nu(tau) appearance, achieved with four candidate events in a subsample of the data, was previously reported. In this Letter, a fifth nu(tau) candidate event, found in an enlarged data sample, is described. Toge...
Study of charged hadron multiplicities in charged-current neutrino-lead interactions in the OPERA detector
Agafonova, N.; et. al. (Springer Science and Business Media LLC, 2018-01-24)
The OPERA experiment was designed to search for nu(mu) -> nu(tau) oscillations in appearance mode through the direct observation of tau neutrinos in the CNGS neutrino beam. In this paper, we report a study of the multiplicity of charged particles produced in charged-current neutrino interactions in lead. We present charged hadron average multiplicities, their dispersion and investigate the KNO scaling in different kinematical regions. The results are presented in detail in the form of tables that can be use...
Results from the OPERA Experiment in the CNGS Beam
Paoloni, Alessandro; et. al. (2018-12-01)
The OPERA experiment was designed to observe v(mu) -> v(tau) oscillations through tau appearance on the CERN Neutrino to Gran Sasso (CNGS) beam over a baseline of 730 km. OPERA was a hybrid experiment composed of lead plates and emulsion layers acting as a target for neutrino interactions. The experiment was complemented with electronic detectors: scintillator strips used as Target Trackers and muon spectrometers. A review of the OPERA final results is presented in this paper.
Procedure for short-lived particle detection in the OPERA experiment and its application to charm decays
Agafonova, N.; et. al. (2014-08-01)
The OPERA experiment, designed to perform the first observation of nu(mu) -> nu(tau) oscillations in appearance mode through the detection of the tau leptons produced in nu(tau) charged current interactions, has collected data from 2008 to 2012. In the present paper, the procedure developed to detect tau particle decays, occurring over distances of the order of 1 mm from the neutrino interaction point, is described in detail and applied to the search for charmed hadrons, showing similar decay topologies as ...
