Updated constraints on sterile neutrino mixing in the OPERA experiment using a new νe identification method / OPERA Collaboration
This paper describes a new νe identification method specifically designed to improve the low-energy (<30GeV) νe 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 νe 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 vτ appearance in a vμ 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 cc¯ 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 νe, νμ and ντ charged current weak neutrino interactions, as well as neutral current weak interactions. [...]

Sensitivity of the SHiP experiment to Heavy Neutral Leptons / SHiP Collaboration
Heavy Neutral Leptons (HNLs) are hypothetical particles predicted by many extensions of the Standard Model. These particles can, among other things, explain the origin of neutrino masses, generate the observed matter-antimatter asymmetry in the Universe and provide a dark matter candidate. [...]

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 νμντ 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. [...]

The experimental facility for the Search for Hidden Particles at the CERN SPS / SHiP Collaboration
The Search for Hidden Particles (SHiP) Collaboration has shown that the CERN SPS accelerator with its 400 GeV/c proton beam offers a unique opportunity to explore the Hidden Sector. The proposed experiment is an intensity frontier experiment which is capable of searching for hidden particles through both visible decays and through scattering signatures from recoil of electrons or nuclei.

Final results of the OPERA experiment on ντ appearance in the CNGS beam / OPERA Collaboration
The OPERA experiment was designed to study νμντ oscillations in appearance mode in the CNGS neutrino beam. In this letter we report the final analysis of the full data sample collected between 2008 and 2012, corresponding to 17.971019 protons on target. [...]
