The COHERENT experiment consists of a suite of neutrino detectors located in a basement hallway at the Spallation Neutron Source in Oak Ridge National Laboratory. In 2017 (and again in 2021) COHERENT reported the first (and second) observation of CEvNS. I will present the status of these measurements. COHERENT is in the process of deploying four new neutrino detectors to "neutrino alley",...

The detection of coherent-neutrino nucleus scattering (CEvNS) opens a new window to study the fundamental properties of neutrinos and to probe physics beyond the Standard Model of Particle Physics. NUCLEUS is a novel cryogenic neutrino experiment at a nuclear power reactor which allows for precision measurements of CEvNS at unprecedentedly low energies. It is based on recently demonstrated...

The IceCube Neutrino Observatory located near the geographical South Pole has measured the spectra of high-energy atmospheric and astrophysical neutrinos. Using the data collected over more than ten years, IceCube has performed searches for new neutrino forces, partners, and space-time symmetries have been performed. This talk will review recent results on beyond Standard Model measurements...

nuBDX-DRIFT is a directional low-pressure TPC detector suitable for measurements of coherent elastic neutrino-nucleus scattering (CEvNS) using a variety of gaseous target materials which include carbon disulfide, carbon tetrafluoride and tetraethyllead. In this talk, I will briefly discuss various aspects of the physics opportunities that measurements using the LBNF beamline offer. Special...

The detection of the cosmic neutrino background (CvB) is an outstanding problem in particle physics and cosmology. We propose a new way to detect CvB via resonant scattering against cosmogenic GZK neutrinos, which leads to an attenuation of the GZK neutrino flux. However, to have any observable effect, we need significant CvB overdensity along the line-of-sight. This might be feasible in...

NOvA is a long-baseline neutrino oscillation experiment designed to observe electron neutrino appearance in a muon neutrino beam. It consists of a near detector at Fermilab and a 14-kt far detector 810 km away in northern Minnesota, both exposed to the NuMI beam. In this talk, I will review recent results from NOvA, including measurements of the neutrino oscillation parameters based on a...

Based on their millimeter resolution and potential on calorimetric capabilities, liquid-argon time-projection chambers (LArTPCs) offer unique opportunities for detection of weakly interacting particles, and have been selected as the technology of the far detector of the Deep Underground Neutrino Experiment (DUNE). While LArTPCs have demonstrated good performance at keV-scale in small-scale...

One of the most important achievements in the field of particle physics was the discovery of neutrino oscillations.
Go to contribution page
Despite already awarded Nobel Prize, neutrino oscillation experiments still have a lot to offer, primarily the discovery
of CP violation in the lepton sector is anticipated. The expression for neutrino oscillation probabilities is composed
of neutrino mixing parameters and... -

In neutrino oscillation physics numerous exact degeneracies exist under the name LMA-Dark.
Go to contribution page
These degeneracies make it impossible to determine the sign of $\Delta m^2_{31}$ known as the atmospheric mass ordering with oscillation experiments alone in the presence of new neutrino interactions.
We discuss the status of these degeneracies and show that recent data has lifted the LMA-Dark... -

The ICARUS collaboration employed the 760-ton T600 detector in a successful three-year physics run at the underground LNGS laboratories studying neutrino oscillations with the CNGS neutrino beam from CERN, and searching for atmospheric neutrino interactions. ICARUS performed a sensitive search for LSND-like anomalous νe appearance in the CNGS beam, which contributed to the constraints on the...

The nature of CP violation in the lepton sector is one of the biggest open questions in particle physics. Long-baseline accelerator neutrino experiments have the opportunity to determine if CP is violated in the mass matrix. I will look at the most recent NOvA and T2K data which show a slight and very interesting tension. While this tension possibly indicates a flipping in the mass ordering,...

We will discuss how to systematically study physics beyond the standard model (BSM) in the neutrino experiments within the Standard Model Effective Field Theory (SMEFT) framework. In this way, the analysis of the data can capture large classes of models, where the new degrees of freedom have masses well above the relevant energy of the experiment. Moreover, it allows us to compare several...

I shall describe the natural origin of Dirac neutrinos with small masses in a class of left-right symmetric theories. These models also solve the strong CP problem via parity symmetry, without the need for an axion. Consistency with neutrino oscillation data will be shown. Such Dirac neutrino models can be tested in CMB measurements of Neff, which is predicted to be larger by about 0.14.
