The Short-Baseline Near Detector (SBND) will be one of three Liquid Argon Time Projection Chamber (LArTPC) neutrino detectors positioned along the axis of the Booster Neutrino Beam (BNB) at Fermilab, as part of the Short-Baseline Neutrino (SBN) Program. The detector is anticipated to begin operation later this year. SBND is characterized by superb imaging capabilities and will record over a...
The MicroBooNE experiment employs an 85-ton active volume liquid argon time projection chamber to detect neutrinos from both the on-axis Booster Neutrino Beam (BNB) and off-axis Neutrinos at the Main Injector (NuMI) beam. This work investigates short baseline neutrino oscillations in a 3+1 sterile neutrino model and compares our results to previous anomalies found in experiments such as LSND,...
The MicroBooNE experiment is an 85-ton active volume liquid argon time projection chamber (LArTPC) neutrino detector situated in the Fermilab Booster Neutrino Beam (BNB). Leveraging the unique capabilities of the LArTPC technology to distinguish photons from electron electromagnetic showers, MicroBooNE has achieved the world's most sensitive search for neutrino-induced single-photon...
The 4.8$\sigma$ low-energy excess (LEE) of electron-like events observed by MiniBooNE is one of the longest-standing anomalies in particle physics. As the MiniBooNE reconstruction relied on the identification of Cherenkov rings, the excess could come from extra electrons or photons in the detector. This talk covers new developments regarding each hypothesis. The MicroBooNE experiment has...
ICARUS is a liquid argon time projection chamber (LArTPC) neutrino detector situated at the intersection of two neutrino beams at Fermilab. As part of the Short-Baseline Neutrino (SBN) program, it will search for neutrino oscillations in the Booster Neutrino Beam (BNB). The search will test past anomalous results in neutrino physics such as the LSND, MiniBooNE, and reactor anomalies which...
Neutrinoless double-beta decay (0ฮฝฮฒฮฒ) 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 Inverted-Ordering...

The detection of Coherent Elastic Neutrino-Nucleus Scattering (CEvNS) performed in 2017 and 2021 with cesium iodide and in 2020 with liquid argon by the COHERENT collaboration has paved the way for precision phenomenological measurements of many diverse physical phenomena.
CEฮฝNS is a neutral...
In the context of the Phenomenological Type I Seesaw, we investigate the LHC's sensitivity to exclusive, mesonic decay modes of long-lived, light (Dirac and Majorana) heavy neutrinos $N$ when they are produced in the decays of $W^\pm$ bosons. We present a new framework that combines massless QCD to describe $N$'s production up to NLO in QCD via weak bosons with a low-energy effective field...
The Large Hadron Collider (LHC) can produce huge numbers of neutrinos into the large rapidity region. New experiments at the LHC, the ongoing FASER\nu and SND@LHC and the proposed Forward Physics Facility (FPF) experiments aim to detect such neutrinos, in particular prompt neutrinos which mainly come from charm hadron decays. Prompt neutrinos can be also produced by cosmic ray interactions in...
Most antineutrinos produced in a nuclear reactor have energies below the inverse beta decay (IBD) threshold, and have not yet been detected. We show that a coherent elastic neutrino-nucleus scattering (CEvNS) experiment with an ultra-low energy threshold like NUCLEUS can measure the flux of reactor neutrinos below the IBD threshold. Using a regularized unfolding procedure, we find that a...
One of the basic foundations of quantum field theory is Lorentz invariance. The spontaneous breaking of Lorentz symmetry at a high energy scale can be studied at low energy extensions like the Standard model in a model-independent way through effective field theory (EFT). The present and future Long-baseline neutrino experiments can give a scope to observe such a Planck-suppressed physics of...
Neutrino oscillation experiments have provided crucial insights into the nature of neutrinos, including the discovery of neutrino oscillations and the observation of CP violation. Non-Standard Neutrino Interactions (NSIs) have emerged as an important topic of study, as they can potentially modify the neutrino oscillation probabilities and affect the measurement of CP violation parameters. In...
The focus of our study is to investigate neutrino mass models that arise from discrete non-abelian modular symmetry groups. These symmetries offer a promising theoretical approach to understanding neutrino phenomenology and involve multiple free parameters. Specifically, we examine models based on the $A_4$ modular symmetry and explore how the non-trivial transformation of Yukawa couplings...
The discovery of new, flavor-dependent neutrino interactions would provide compelling evidence of physics beyond the Standard Model. We focus on interactions generated by the anomaly-free, gauged, abelian lepton-number symmetries, specifically $L_e-L_\mu$, $L_e-L_\tau$, and $L_\mu-L_\tau$, that introduce a new matter potential sourced by electrons and neutrons, potentially impacting neutrino...
The IceCube Neutrino Observatory is the largest neutrino telescope located deep within the South Pole ice. Currently, an upgrade with denser spaced sensors is being built and one of the goals of the IceCube Upgrade is a precise characterization of the optical properties of the Antarctic ice, which is the source of the largest systematic uncertainty for most IceCube analysis. Calibration...
The Super-Kamiokande water Cherenkov underground neutrino observatory is located in Japan. Since 2020, it has undergone two loadings with gadolinium sulfate. In the first loading during summer 2020, 13 tons of gadolinium sulfate octahydrate were dissolved, corresponding to a mass concentration of 0.02% gadolinium sulfate. In the second loading, 26 tons were diluted, resulting in a mass...
Coherent elastic neutrino-nucleus scattering (CEvNS) was predicted in 1974 as a consequence of the weak neutral current. 43 years later, the COHERENT collaboration first observed CEvNS using a 14.6-kg CsI detector. After 3 years, CEvNS on argon was measured using COH-Ar-10 (CENNS-10), 24-kg liquid argon detector. There are many physics opportunities related to CEvNS, but COH-Ar-10 has ~30%...
The Short Baseline Near Detector (SBND), a 112 ton liquid argon time projection chamber (LArTPC), is the near detector of the Short Baseline Neutrino Program at Fermilab. In a LArTPC, ionization electrons from a charged particle track drift along the electric field lines, inducing bipolar signals on the induction planes, and a unipolar signal collected on the collection plane. In this talk, I...
The Deep Underground Neutrino Experiment (DUNE) is a precision long-baseline neutrino oscillation experiment that will employ LArTPC technology in a near detector placed at Fermilab and a far detector at the Sanford Underground Research Facility, at a baseline of 1300 km. The DUNE Liquid Argon Near Detector (ND-LAr) design takes into account the high neutrino intensity expected from the LBNF...
Monitored neutrino beams represent a powerful and cost effective tool to suppress cross section related systematics for the full exploitation of data collected in long baseline oscillation projects like DUNE and Hyper-Kamiokande. In the last years the NP06/ENUBET project has demonstrated that the systematic uncertainties on the neutrino flux can be suppressed to 1% in an accelerator based...
The upcoming long baseline neutrino experiments have the goal of enhancing proton beam power to a multi-MW scale and utilizing large-scale detectors to address the challenge of limited event statistics. The DUNE experiment at LBNF will test the three neutrino flavor paradigm and directly search for CP violation by studying oscillation signatures in the high intensity $\nu_{\mu}$...
We have studied the capability of different long-baseline experiment options at the KM3NeT facility i.e., P2O, Upgraded P2O and P2SO to probe the light sterile neutrino and compare their sensitivities with DUNE. The P2O option will have neutrinos from a 90 KW beam at Protvino to be detected at the ORCA detector, the Upgraded P2O will have neutrinos from the upgraded 450 KW beam to be detected...
Although the existence of dark matter has been well established by numerous observations, its nature remains unknown. Dark Matter could be detected indirectly through the observation of neutrinos produced in self-annihilations or decays of dark matter. Objects with large dark matter accumulations such as galaxy clusters or the Galactic dark matter halo are primary targets. Searches for such...
Some properties of a neutrino may differ significantly depending on whether it is Dirac or Majorana type. The type is determined by the relative size of Dirac and Majorana masses, which may vary if they arise from an oscillating scalar dark matter. We show that the change can be significant enough to convert the neutrino type between Dirac and Majorana while satisfying constraints on the dark...
The exquisite capabilities of liquid Argon Time Projection Chambers make them ideal to search for weakly interacting particles in Beyond the Standard Model scenarios. Given their location at CERN the ProtoDUNE detectors may be exposed to a flux of such particles, produced in the collisions of 400 GeV protons (extracted from the Super Proton Synchrotron accelerator) on a target. Here we point...
The accelerator complex at Fermilab is currently undergoing improvements which will increase the available beam power to the complex and is known as Proton Improvement Plan-II (PIP-II). The PIP-II Linac is slated for operation near the end of this decade and will be the main proton driver for Fermilab experiments moving forward and provide the beam to LBNF/DUNE. However, the DUNE physics...
The Short-Baseline Near Detector (SBND) is a 112-ton liquid argon time projection chamber (LArTPC) detector located 110-meters downstream the Booster Neutrino Beam target at Fermilab. As the near detector of the Short-Baseline Neutrino Program, SBND is especially sensitive to any new particles produced in the beam. In addition to the excellent spatial and energy resolution of the LArTPC...
