Coherent elastic neutrino-nucleus scattering (CEvNS) is a process in which a neutrino scatters off an entire nucleus. Measurements will further the search for BSM physics and bring new insights to topics in nuclear physics and astrophysics. CEvNS has now been observed in CsI and Ar by the COHERENT collaboration. A number of experiments are pursuing further measurements, making use of a...
The CONUS experiment aims at detecting coherent elastic neutrino nucleus scattering (CE$\nu$NS) at the nuclear power plant in Brokdorf, Germany, which has a maximum thermal power of 3.9GW$_{th}$. Four low energy threshold high-purity point contact Germanium spectrometers are set up in an elaborate shield achieving background levels comparable to experiments located much deeper...
Detection of coherent elastic neutrino nucleus-scattering (Cevns) has been recently confirmed. The low-energy region of this process and its neutral current character, allows to explore beyond the Standard Model particle physics in complementary regions to other searches. In this talk I will review the current status and future perspectives of such constraints with a special focus on...
The recent observation of coherent elastic neutrino nucleus scattering (CEvNS) has opened new opportunities for investigating nuclear structure parameters and other electroweak probes. In this talk I will present the current status of constraints on the nuclear neutron rms radii of CsI and Argon, placed by the COHERENT data. I will also review the implications of advanced nuclear structure...
In this talk we will present the first measurement of the neutron skin of cesium and iodine using electroweak probes, coherent elastic neutrino-nucleus scattering and atomic parity violation. This measurement, differently from hadronic probes, is model-independent and suggests a preference for nuclear models which predict large neutron skin values, with implications that range from neutron...
T2K is an accelerator-based neutrino experiment providing world-leading measurements of the parameters governing neutrino oscillation. T2K data enabled the first 3sigma exclusion for some intervals of the CP-violating phase \delta_{CP} and precision measurements of the atmospheric parameters \Delta_m^{2}{32}, sin^2(\theta{23}). T2K uses a beam of muon neutrinos and antineutrinos produced at...
The NOvA experiment is a long-baseline accelerator-based neutrino oscillation experiment that uses the upgraded NuMI beam from Fermilab to measure electron-neutrino appearance and muon-neutrino disappearance between the Near Detector, located at Fermilab, and the Far Detector, located at Ash River, Minnesota. NOvA's primary physics goals include precision measurements of oscillation...
The Jiangmen Underground Neutrino Observatory (JUNO) is a multi-purpose neutrino experiment currently under construction in South China, expecting to start data taking in 2023. JUNO primary goal is the determination of the neutrino mass ordering and the measurement at a sub-percent level three of the neutrino oscillation parameters and thanks to the detection of reactor antineutrinos at a...
In this talk, I will present the current status of global analyses to neutrino oscillation data in the three-flavor framework. I will discuss the recent hints in favor of normal mass ordering and maximal CP violation and the tensions that appear from the combination of different data samples. I will also comment on future opportunities to improve our knowledge of the oscillation picture as...
Search for eV Sterile Neutrinos -- The STEREO Experiment
Mathieu Vialat on behalf of the STEREO collaboration\
In the recent years, the study of reactor antineutrinos has revealed two unsolved anomalies. The first one is related to the neutrino spectral shape where an excess of detected neutrinos compared to the model is observed around $5~$MeV. The second anomaly, called Reactor...
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...
SND@LHC is a compact and stand-alone experiment to perform measurements with neutrinos produced at the LHC in a hitherto unexplored pseudo-rapidity region of 7.2 < η < 8.6, complementary to all the other experiments at the LHC. The experiment is to be located 480 m downstream of IP1 in the unused TI18 tunnel. The detector is composed of a hybrid system based on an 800 kg target mass of...
Double beta decay tests new physics beyond the standard model. Various theoretical options and methods to unravel which one is realized will be discussed.
The search for neutrinoless double-beta decay is generally quoted as the only practical way to establish the nature of the mass of neutrino, one of the most elusive and intriguing elementary particles in the Standard Model. The detection of this rare nuclear decay would attribute to neutrino special properties, described for the first time by Ettore Majorana at the beginning of the last...
The Cryogenic Underground Observatory for Rare Events (CUORE) is the first bolometric experiment searching for 0νββ decay that has been able to reach 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...
SNO+ is a large volume liquid scintillator experiment for neutrino physics located at SNOLAB, Canada. Using the 12 m diameter acrylic vessel and the PMT array of the SNO detector, SNO+ has the primary physics goal of searching for the neutrinoless double-beta decay of the 130Te isotope. Data collected will also be used to explore additional physics topics such as reactor antineutrino...
Since neutrinos have no electric charge or color, they may be their own antiparticles, referred to as Majorana neutrinos, and thus violate lepton number conservation. Neutrinoless double beta decay (0νββ) would be a direct consequence, and the search for this decay mode is the most sensitive method to unravel the Majorana nature of neutrinos. In this talk, I will high-light recent experimental...
Project 8 is a next-generation direct neutrino mass experiment measuring the spectral endpoint region of tritium beta decays. The energy of the beta decay electrons is measured using Cyclotron Radiation Emission Spectroscopy (CRES) which has been demonstrated by the Project 8 collaboration with krypton or molecular tritium confined in a section of a microwave guide. To reach the target...
Borexino has now been observing the Sun shining in neutrinos since over 14 years. The last and among the most important results obtained with this large liquid scintillator detector at the underground Laboratori Nazionali del Gran Sasso is the discovery of neutrinos from the Carbon-Nitrogen-Oxygen (CNO) cycle of fusion reactions.
Previously unobserved, the CNO cycle is predicted to be a...
Precision measurements of the flavor oscillations of atmospheric neutrinos have the potential to reveal several phenomena beyond the Standard Model. The DeepCore sub-array of the IceCube neutrino telescope is capable of detecting large amounts of atmospheric neutrinos at energies as low as 5 GeV, which allows for observations of neutrino oscillations via muon neutrino disappearance. A new...
It is known that the lepton mixing angles are completely different from the quark mixing angles. The fundamental principle behind the flavor mixing structure remains unknown. I will review the different approaches to predict the lepton mixing angles and the Dirac and Majorana CP violation phases from theory, commenting also on their experimental tests. Their implications in neutrino...
The ability of current and next generation accelerator based neutrino oscillation measurements to reach their desired sensitivity requires a high-level of understanding of the neutrino-nucleus interactions. These include precise estimation of the relevant cross sections and the reconstruction of the incident neutrino energy from the measured final state particles. Incomplete understanding of...
The Deep Underground Neutrino Experiment (DUNE) is a next generation, long-baseline neutrino oscillation experiment which will utilize high-intensity $\nu_{\mu}$ and $\bar{\nu}_{\mu}$ with peak neutrino energies of ~2.5 GeV produced at Fermilab, over a 1285 km baseline, to carry out a detailed study of neutrino mixing. The neutrino beam has an initial design intensity of 1.2 MW, but has a...
