Updated constraints on sterile neutrino mixing in the OPERA experiment using a new $\nu_e$ identification method / OPERA Collaboration
This paper describes a new $\nu_e$ identification method specifically designed to improve the low-energy ($< 30\,\mathrm{GeV}$) $\nu_e$ identification efficiency attained by enlarging the emulsion film scanning volume with the next generation emulsion readout system. A relative increase of 25-70% in the $\nu_e$ low-energy region is expected, leading to improvements in the OPERA sensitivity to neutrino oscillations in the framework of the 3 + 1 model. [...]

OPERA tau neutrino charged current interactions / OPERA Collaboration
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. [...]

First observation of a tau neutrino charged current interaction with charm production in the Opera experiment / OPERA Collaboration
An event topology with two secondary vertices compatible with the decay of short-lived particles was found in the analysis of neutrino interactions in the Opera target. The observed topology is compatible with tau neutrino charged current (CC) interactions with charm production and neutrino neutral current (NC) interactions with $c\overline{c}$ pair production.

Final results on neutrino oscillation parameters from the OPERA experiment in the CNGS beam / OPERA Collaboration
The OPERA experiment has conclusively observed the appearance of tau neutrinos in the muon neutrino CNGS beam. Exploiting the OPERA detector capabilities, it was possible to isolate high purity samples of $\nu_{e}$, $\nu_{\mu}$ and $\nu_{\tau}$ charged current weak neutrino interactions, as well as neutral current weak interactions.

Latest results of the OPERA experiment on nu-tau appearance in the CNGS neutrino beam / OPERA Collaboration
OPERA is a long-baseline experiment designed to search for $\nu_{\mu}\to\nu_{\tau}$ oscillations in appearance mode. It was based at the INFN Gran Sasso laboratory (LNGS) and took data from 2008 to 2012 with the CNGS neutrino beam from CERN. [...]

Measurement of the cosmic ray muon flux seasonal variation with the OPERA detector / OPERA Collaboration
The OPERA experiment discovered muon neutrino into tau neutrino oscillations in appearance mode, detecting tau leptons by means of nuclear emulsion films. The apparatus was also endowed with electronic detectors with tracking capability, such as scintillator strips and resistive plate chambers. [...]

Final results of the search for $\nu_{\mu} \to \nu_{e}$ oscillations with the OPERA detector in the CNGS beam / OPERA Collaboration
The OPERA experiment has discovered the tau neutrino appearance in the CNGS muon neutrino beam, in agreement with the 3 neutrino flavour oscillation hypothesis. The OPERA neutrino interaction target, made of Emulsion Cloud Chamber, was particularly efficient in the reconstruction of electromagnetic showers. [...]
