The Short-Baseline Near Detector (SBND) is a 112-ton liquid argon time projection chamber 110 m away from the Booster Neutrino Beam (BNB) target at Fermilab (Illinois, USA). The close location to the BNB origin makes the experiment sensitive to physics beyond the Standard Model (BSM) produced in the beam. Thanks to its advanced scintillation light detection system, a timing resolution at the...

MicroBooNE is an 85-tonne active mass liquid argon time projection chamber (LArTPC) at Fermilab. Between 2015-2021, the detector recorded neutrino interactions from the Booster Neutrino Beam (BNB) and Neutrinos at the Main Injector (NuMI) beams. MicroBooNE's capabilities for fine-grained tracking, particle identification, and calorimetry make it a powerful detector not just to explore neutrino...

High energy collider neutrinos have been observed for the first time by the FASER$\nu$ experiment. The detected spectrum of collider neutrinos scattering off nucleons can be used to probe neutrinophilic mediators with GeV-scale masses. We perform an analysis on the measured muon spectra at FASER$\nu$, and find that the bounds on the vector mediator from the current FASER$\nu$ data are...

The Short-Baseline Near Detector (SBND) is one of three Liquid Argon Time Projection Chamber (LArTPC) detectors used in the Short-Baseline Neutrino (SBN) programme at Fermilab. As the near detector in the SBN programme, the SBND is located just 100 metres from the target along the Booster Neutrino Beam (BNB). SBND offers sensitivity to a broad range of new physics scenarios, including the...

The standard approach to observing Time reversal (T) symmetry violation formally corresponds to exchanging neutrino flavors of the neutrino source and detector, which is experimentally challenging. We propose an alternative framework to test T violation without interchanging the source and detector, but using the L-odd components in the transition probabilities. We compare the data at...

The JUNO detector (Jiangmen Underground Neutrino Observatory), located in Jiangmen, southern China, is currently in its commissioning phase. Its main goal is to determine the neutrino mass ordering and to reduce uncertainties on oscillation parameters. Thanks to its huge liquid scintillator mass (20 kton), its high radiopurity and excellent energy resolution, JUNO is an ideal candidate to...

The KATRIN experiment is designed to measure the mass of the electron antineutrino by studying the high-energy end of the tritium β decay spectrum. In addition, KATRIN is also a well-suited instrument to explore the sterile neutrino hypothesis. The existence of sterile neutrinos would cause a kink-like distortion in the spectrum.
Using the same datasets as for active neutrino mass, KATRIN...
