The Neutrinos Angra Experiment, a ton-scale gadolinium-loaded water Cherenkov detector, is located approximately 30 meters from the Angra-II power plant in Angra dos Reis, Brazil. Its primary objective is to detect electron antineutrinos produced by the reactor and demonstrate the feasibility of using antineutrino detectors for real-time reactor monitoring with a surface detector. This effort...

We evaluate the cross section of inverse beta decay, including all theoretical uncertainties. We focus on the moderate energy range from a few MeV up to hundreds of MeV, which includes neutrinos from reactors and supernovae. We assess the uncertainty on the cross section, which is relevant to experimental advances and increasingly large statistical samples. We also present a new...

The Deep Underground Neutrino Experiment (DUNE) is an international collaboration of 1000+ researchers which will study neutrinos and search for phenomena predicted by theories Beyond the Standard Model (BSM). DUNE will use liquid argon time projection chambers (LArTPCs) containing 70 ktons of LAr, 40 ktons of which are active, located more than a kilometer underground. The high spatial...

Grand Unified Theories explain the unification of the electromagnetic, weak, and strong forces and most of them predict protons to decay into lighter particles. The latest result of the proton decay search for $p\rightarrow e^+/\mu^+ +\eta$ channels in Super-Kamiokande will be discussed in this presentation.

Liquid Argon (LAr) Time Proportional Chambers (TPCs), is one of the most widely used scintillators in particle detection, due to its low cost, high availability and excellent scintillation properties. A large number of experiments in the neutrino sector are based around using LAr in one or more TPCs, leading to high resolution three-dimensional particle reconstruction. We present a first...

Double beta plus decay is a rare nuclear disintegration process. Difficulties in its measurement arise from suppressed decay probabilities, experimentally challenging decay signatures and low natural abundances of suitable candidate nuclei. In this presentation, we propose NuDoubt++, a new detector concept to overcome these challenges. It is based on the first-time combination of hybrid and...

Eos is a 20-ton neutrino detector located on the University of California Berkeley campus. It is a hybrid technology demonstrator that utilizes Cherenkov and scintillation light simultaneously to detect particle interactions. Construction was finished in early 2024. It has a fiducial volume of four-ton, featuring 242 photomultiplier tubes, including ultra-fast PMTs and dichroicons for spectral...

The detection of high-energy astrophysical neutrinos by IceCube has unveiled a new way to observe our Universe. Despite IceCube's success in measuring the high-energy astro flux up to energies reaching several PeV, much remains to be discovered regarding their origin and nature. The identification of high-energy astro-neutrino sources is largely hindered by atmospheric neutrino backgrounds;...

In this letter we are using the IceCube experiment to test, phenomenologically, the (3+2) sterile neutrino scenario. As far is known, the presence of sterile states with mass splitting ∆m²∼1 eV² distorts the angular and energy distributions of reconstructed muon events, observed by IceCube, through parametric and MSW resonances. Since the distortions introduced by the sterile neutrino (3+2)...

We consider the decoherence effects in the propagation of active neutrinos due to the non-forward neutrino scattering processes in a matter background composed of normal matter. We calculate the contribution to the imaginary part of the neutrino self-energy arising from such processes. Since the initial neutrino state is depleted but does not actually disappear (the initial neutrino...
