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. However, other processes can mimic this topology. A dedicated analysis was implemented to identify the underlying process. A Monte Carlo...

The GERmanium Detector Array (Gerda) is a low background experiment located at the Laboratori Nazionali del Gran Sasso in Italy, which searches for neutrinoless double-beta decay of \(^{76}\)Ge into \(^{76}\)Se+2e\(^-\). Gerda has been conceived in two phases. Phase II, which started in December 2015, features several novelties including 30 new 76Ge enriched detectors. These were manufactured according to the Broad Energy Germanium (BEGe) detector design that has a better background discriminati...
In this work, the ^{222}n contamination mechanisms on acrylic surfaces have been investigated. ^{222}n can represent a significant background source for low-background experiments, and acrylic is a suitable material for detector design thanks to its purity and transparency. Four acrylic samples have been exposed to a ^{222}n rich environment for different time periods, being contaminated by ^{222}n and its progenies. Subsequently, the time evolution of radiocontaminants activity on t...

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. In this Letter, the full dataset is used for the first time to test the three-flavor neutrino oscillation model and to derive constraints on the existence of a light...

The GERmanium Detector Array (GERDA) experiment at the Gran Sasso underground laboratory (LNGS) of INFN is searching for neutrinoless double-beta (0\nu\beta\beta decay of ^{76}e. The technological challenge of GERDA is to operate in a background-free regime in the region of interest (ROI) after analysis cuts for the full 100 kg\cdot target exposure of the experiment. A careful modeling and decomposition of the full-range energy spectrum is essential to predict the shape and composition ...

Abstract The GERDA experiment searches for the lepton number violating neutrinoless double-beta decay of 76Ge operating bare, enriched Ge diodes in liquid argon. The broad energy germanium (BEGe) detectors, feature an excellent background discrimination from the analysis of the time profile of the detector signals, while the instrumentation of the cryogenic liquid volume surrounding the germanium detectors acts as an active veto to further suppress the external background. With a total exposure ...
