The latest results of the DANSS experiment are presented. DANSS is a one cubic meter highly segmented solid scintillator detector. It consists of 2500 scintillator strips, covered with gadolinium loaded reflective coating and read out with SiPMs and PMTs via wavelength shifting fibers. DANSS is placed under a 3.1 GW industrial reactor at the Kalinin NPP (Russia) on a movable platform. The...
In this work we derive limits on the WIMP-nucleon scattering cross-section by comparing the potential heat flow within the Earth from Dark Matter capture and subsequent annihilation to the observational value. This effect has been argued previously in the literature to provide a potential link to mass extinction phenomena on Earth. However, we focus on whether additional heat-flux from dark...
Darkside-20k, an underground dark matter search experiment located at
LNGS (Italy), aims to achieve a total exposure of 200 tonne-years
devoid of instrumental backgrounds. At its core is a dual-phase Time
Projection Chamber (TPC) containing 50 tonnes of low-radioactivity
liquid argon. Surrounding the entire TPC wall is a gadolinium-loaded
acrylic material, serving as a neutron veto. This...
Since the beginning of its full operation in 2011, the IceCube Neutrino Observatory at the South Pole station, has pioneered many discoveries in neutrino astronomy, cosmic ray physics, and particle physics. This talk will present the experiment, and highlight recent discoveries, such as the evidence for neutrino emission from the active galactic nucleus NGC 1068, the first observation of...
The KM3NeT collaboration is constructing two last-generation underwater neutrino telescopes in two abyssal sites of the Mediterranean Sea. The scientific goal is to complement the IceCube sky coverage, instrumenting a comparable detection volume and improving the reconstruction accuracy.
Each telescope is a Cherenkov detector built with the same technologies but with a different geometrical...
Neutrino experiments based on water-Cherenkov detectors have made significant contributions
to our understanding of neutrino physics, but they face challenges in accurately modeling
detector systematic parameters due to their large size and the smallness of the cross-section
for weak interactions. While these experiments have achieved remarkable successes in the
past, the future era of...
SBND is a 112-ton liquid argon time projection chamber located on the Booster Neutrino Beam at Fermi National Accelerator Laboratory, and is the near detector of the Short-Baseline Neutrino program. The primary goals of SBND are to provide flux constraints for sterile neutrino searches, conduct world-leading neutrino cross-section measurements on argon, and perform beyond the Standard Model...
The ANTARES detector is an underwater Cherenkov neutrino telescope. Its construction was completed in 2008 and it operated for sixteen years in the Mediterranean Sea. Even though optimised for the search for cosmic neutrinos, this telescope is also sensitive to exotic particles like magnetic monopoles and nuclearites (massive nuggets of strange quark matter). We discuss here the possible...
We discuss as accurately as possible the cross section of quasi-elastic scattering of electron (anti-)neutrinos on nucleons, also known as inverse beta decay in the case of antineutrinos. 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...
The experimental and theoretical research on the physics of massive neutrinos is based on the standard paradigm of three-neutrino (3ν) mixing, which describes the oscillations of neutrino flavors measured in solar, atmospheric and long-baseline experiments. However, several anomalies are short baseline oscillation data, corresponding to an L/E of about 1m/MeV could be interpreted by involving...
The SND@LHC experiment at the Large Hadron Collider is a new neutrino scattering experiment, that got approved and installed in 2021.
We report the direct observation of muon neutrino interactions with the SND@LHC detector using a dataset of proton-proton collisions at 13.6 TeV collected in 2022 and corresponding to an integrated luminosity of 36.8 fb−1. The search is based on information...
The Majorana nature of the neutrino, i.e., whether it is its own antiparticle, remains an open problem in modern physics. The observation of Neutrinoless Double Beta Decay (0$\nu\beta\beta$), a hypothesized beyond Standard Model process, would conclusively establish the Majorana nature of neutrinos. It would also demonstrate lepton number violation and could provide insight into the absolute...
We discuss a new experiment based on the proposal [1] to observe for the first time the coherent elastic neutrino-atom scattering (CEνAS), using electron antineutrinos from tritium decay and a liquid He-4 target, and also to search neutrino electromagnetic properties [2], including the neutrino magnetic moment. The experiment is under preparation within the research program of the National...
The ICARUS collaboration has employed the 760-ton T600 detector in a successful three-year physics run at the underground LNGS laboratory, performing a sensitive search for LSND-like anomalous $\nu_e$ appearance in the CERN Neutrino to Gran Sasso beam, which contributed to the constraints on the allowed neutrino oscillation parameters to a narrow region around 1 eV$^2$. After a significant...
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...
Precise knowledge of how neutrinos interact with matter is essential for measuring neutrino oscillations in long-baseline experiments. At the T2K experiment, the near detector complex measures neutrino interactions to constrain cross section models for oscillation studies and characterises the beam flux. In addition, the near detector complex provides a separate platform for performing...
The Deep Underground Neutrino Experiment (DUNE) is a long-baseline neutrino oscillation experiment currently in construction and expected to take data in late 2020s. In order to explore a wide range of physics, from precise measurements of the neutrino oscillation parameters to proton decay and supernova neutrino detection, it will comprise a far detector complex located in the Sanford...
Searches for new physics are conducted in different experimental conditions, e.g. at high energy colliders or with high intensity particle beams. The Deep Underground Neutrino Experiment (DUNE) will be a powerful tool for the study of a variety of physics topics, due to its high-intensity proton beams that provide large neutrino fluxes, and which are sampled by a near detector system...
The Jiangmen Underground Neutrino Observatory (JUNO) is a multi-purpose neutrino experiment currently under construction in southern China.
The detector consists of a 35.4 m diameter acrylic sphere filled with 20 kton of ultra-pure liquid scintillator and makes JUNO the largest LS-based, underground neutrino observatory capable of addressing many important topics in different fields of...
