The MicroBooNE liquid argon time projection chamber (LArTPC) experiment operated in the Fermilab Booster Neutrino and Neutrinos at the Main Injector beams from 2015-2021. Among the major physics goals of the experiment is a detailed investigation of neutrino-nucleus interactions. MicroBooNE currently possesses the world's largest neutrino-argon scattering data set, and more than 30 ongoing...
The MINERvA experiment at Fermilab presents results from quasielastic-like (QE-like) $\nu_{\mu}$ interactions on a variety of nuclear targets in the medium energy ($<$E$_{\nu}>\sim$6~GeV) NuMI neutrino beam. In the analysis described here, events are used where protons are cleanly reconstructed. Cross section and cross section ratio results from events produced on C, CH, H$_{2}$O, Fe, and...
Precise knowledge of how neutrinos interact with matter is essential for measuring neutrino oscillations in long-baseline experiments. At T2K, the near detector complex measures neutrino interactions to constrain cross-section models for oscillation studies and to characterise the beam flux. The near detector complex provides a platform for performing neutrino-nucleon cross section...
In current measurements of neutrino properties with accelerator-based neutrino experiments, neutrino flux uncertainties represent a leading systematic uncertainty. Neutrino beams are created from the decays of hadrons produced in hadron-nucleus interactions. Primary and secondary hadron production processes are the leading source of the flux uncertainty. To constrain the neutrino flux...
Liquid Argon Time Projection Chamber (LArTPC) detectors offer charged particle imaging capability with impressive spatial resolution. Precise event reconstruction procedures are mandatory in order to fully exploit the potential of this technology.

The Short Baseline Neutrino Program at Fermilab aims to confirm or rule out the existence of sterile neutrinos at the eV mass scale. The program will perform the most sensitive search in both electron-neutrino appearance and muon-neutrino disappearance channels along the Booster Neutrino Beamline. The far detector, ICARUS-T600, is a high-granularity Liquid Argon Time Projection chamber located...
The Cryogenic Underground Observatory for Rare Events (CUORE) is the first bolometric experiment searching for 0νββ decay that has successfully reached the one-tonne mass scale. The detector, located at the LNGS in Italy, consists of an array of 988 TeO2 crystals arranged in a compact cylindrical structure of 19 towers. CUORE began its first physics data run in 2017 at a base temperature of...
Neutrinoless double-beta decay (0$\nu\beta\beta$) is a key process to address some of the major outstanding issues in particle physics, such as the lepton number conservation and the Majorana nature of the neutrino. Several efforts have taken place in the last decades in order to reach higher and higher sensitivity on its half-life. The next-generation of experiments aims at covering the...
SNO+ is a large multipurpose experiment located in the SNOLAB underground laboratory in Sudbury, Canada. With an extensive physics programme focused on many neutrino physics topics and nucleon decay searches, the ultimate goal of SNO+ is the search for the neutrinoless double beta decay of ${}^{130}$Te. After a commissioning phase with water as the target medium, whose data allowed...
The LEGEND experiment is designed to search for the neutrinoless double beta (0νββ) decay of the germanium isotope Ge-76. This decay, if observed, would establish the Majorana nature of neutrinos and reveal lepton number non-conservation. The first stage of the experiment, LEGEND-200, has recently completed its commissioning phase and transitioned to physics data taking in March 2023....
The GERmanium Detector Array (GERDA) experiment at the Laboratori Nazionali del Gran Sasso (LNGS, Italy) searched for the lepton-number-violating neutrinoless double-beta ($0\nu\beta\beta$) decay of $^{76}$Ge. The potential discovery of such phenomenon would have significant implications in cosmology and particle physics, helping unrevealing the Majorana nature of neutrinos.
The main...
The Daya Bay Reactor Neutrino Experiment is located next to six commercial nuclear reactors, each of which has a max thermal power of 2.9 GW. The experiment consists of two near experimental halls and one far experimental hall. The power-weighted baselines to the six power reactors are about 500 m and 1.7 km for the near and far halls, respectively. Each near hall has two antineutrino...
FASER, the ForwArd Search ExpeRiment, is an LHC experiment located 480 m downstream of the ATLAS interaction point, along the beam collision axis. FASER and its sub-detector FASERnu have two physics goals: (1) to detect and study TeV-energy neutrinos, the most energetic neutrinos ever detected from a human-made source, and (2) to search for new light and very weakly-interacting particles....
Measuring neutrino mass is challenging in nowadays particle physics and astrophysics. Direct measurements using electron kinematics in beta decays are the only theory-independent method. A possible approach for directly measuring the neutrino mass is the calorimetric one. Calorimeters measure the energy released by decays, except the neutrino fraction. However, they face limitations in...
The CONUS experiment (COherent elastic NeUtrino nucleus Scattering) aims at coherent elastic neutrino-nucleus scattering (CEνNS) with germanium detectors in the Brokdorf Nuclear Power Plant (KBR, Germany). Four 1kg modules were placed 17m from the 3.9GW reactor core, monitoring an energy regime down to sub-keV with a background rate of ~10 per day per keV. Data taking was finished and latest...
Neutrinos are the most elusive particles in the Standard Model, and many of their properties have not yet been fully understood. Among them, neutrino electromagnetic properties such as neutrino charge radius, magnetic moment and milli-charge have become objects of extensive research. Consequently, there is a pressing need for experiments capable of precisely probing them at a high precision...
New results from the DANSS experiment on the searches for sterile neutrinos are presented. They are based on 7 million inverse beta decay events collected at 10.9, 11.9, and 12.9 meters from the 3.1 GW reactor core of the Kalinin Nuclear Power Plant in Russia. Additional 1 million of antineutrino events further improves the sensitivity for the sterile neutrino mixing parameter below 0.01 for a...
T2K is a long baseline neutrino experiment which exploits a neutrino and antineutrino beam produced at the Japan Particle Accelerator Research Centre (J-PARC) to provide world-leading measurements of neutrino oscillation. Neutrino oscillations are measured by comparing neutrino rates and spectra at a near detector complex, located at J-PARC, and at the water-Cherenkov far detector,...
We study in detail the impact of a light sterile neutrino on the interpretation of the recent data of the long baseline experiments NO$\nu$A and T2K, assessing the robustness/fragility of the estimates of the standard 3-flavor parameters with respect to the perturbations induced in the 3+1 scheme. We find that all the basic features of the 3-flavor analysis, including the weak indication...
The IceCube DeepCore detector located at the South Pole has been collecting GeV-scale atmospheric neutrino data for the past decade. At these energies, Earth-crossing muon neutrinos have a high chance of oscillating to tau neutrinos. DeepCore is able to measure the atmospheric oscillation parameters with a precision comparable to accelerator-based experiments, while also complementing...
Neutrino Mass Ordering (NMO) studies explore the unresolved fundamental question of whether the neutrino masses follow a normal ordering (m3>m2>m1) or an inverted ordering (m2>m1>m3). IceCube is an ice-Cherenkov neutrino detector deployed about 1.5 kilometers below the surface of the South Pole. Using DeepCore, a more densely instrumented volume of ice near the bottom of the detector, we study...
