Non-Accelerator-Based Neutrino
The IceCube Neutrino Observary instruments about 1 km^3 of deep, glacial ice below the geographic South Pole with 5160 digital optical modules (DOMs) to register the Cherenkov light of passing charged particles. The DeepCore subdetector, a more densely instrumented region located in the clearest section of ice, provides sensitivity to neutrinos in the range of 5-100 GeV.
Using the DeepCore...

The measurement of the Neutrino Mass Ordering (NMO), i.e. the ordering of the neutrino mass eigenstates, is one of the major goals of many future neutrino experiments. One strategy is to measure matter effects in the oscillation pattern of atmospheric neutrinos as proposed for the PINGU extension of the IceCube Neutrino Observatory. Already, the currently running IceCube/DeepCore detector can...

Located at the South Pole Station in Antarctica, the IceCube Neutrino Observatory is the world's largest neutrino telescope. In the clearest part of the ice sits a more densely instrumented section, DeepCore, that is able to measure neutrinos from 5-80 GeV. Using DeepCore, neutrino oscillations can be observed via $\nu_{\mu}$ disappearance. This talk will highlight the new and greatly improved...

Non-Accelerator-Based Neutrino
IceCube, a neutrino detector located at the South Pole, is an ideal testing ground for the hypothetical 1 eV sterile neutrino, which is motivated by the short-baseline neutrino anomalies. In a normal ordering 3+1 sterile neutrino scheme, the decay of the heaviest neutrino mass eigenstate to lighter eigenstates is unconstrained. In this talk, we will show how such a decay could modify the...

Non-Accelerator-Based Neutrino
We revisit the atmospheric neutrino flux at high energies where the decay of charmed hadrons produced in cosmic ray airshowers is expected to dominate the flux. The forward production of charmed hadrons can potentially increase the predicted flux but it is relatively uncertain due to lack of forward coverage from modern colliders. Using archival data, IceCube atmospheric neutrino flux...

Recent short baseline results have indicated anomalies consistent with ~1 eV2 sterile neutrinos. However, these results are in tension with other null searches, including that of IceCube. This talk will present the most recent global fit results, including IceCube, discuss the source of the tension, in particular the MiniBooNE neutrino result, and present directions of future attack on the...

The Daya Bay experiment has utilized eight functionally identical underground detectors to sample reactor antineutrino fluxes from three pairs of nuclear reactors in South China, accruing the largest reactor antineutrino sample to date. This talk will summarize Daya Bay’s most recent result, which presents observations of correlations between reactor core fuel evolution and changes in the...

Data taken in the MINOS+ configuration have been combined with the already-significant MINOS data set to provide a fertile ground to look for sterile neutrinos in the Fermilab NuMI beam using two detectors separated by a baseline of 734km. The new results, which include half the total MINOS+ exposure and cover a very large range of parameter space, will be presented.

Recent results from the NOvA long-baseline neutrino oscillation experiment are beginning to constrain the parameters of the standard model neutrino properties. Intriguing results using the full data set combining measurements have provided some intriguing results that will be closely watched as data taking continues.

A comparison of neutrino oscillation measurements with those of anti-neutrino oscillation measurements may give information on CP violation in the lepton sector. In this talk, we present the latest results from T2K obtained using both neutrino and anti-neutrino data, which exclude CP conservation at the 90% CL.

A proper understanding of neutrino cross sections is crucial for the precise determination of the neutrino oscillation parameters. The T2K near detectors allow for a range of cross-section measurements on various target materials, often in an energy regime with few previous measurements. This talk will detail some of the recent cross-section results from T2K.

The CHIPS detector (10 kt ) will be deployed in a flooded mine pit in the path of the NuMI beam in 2018.
The detector design has been informed from two years of prototype work where a small detector was
deployed in the Wentworth 2E pit, N. Minnesota. Detector plane and readout design has largely been fixed.
The goal of the experiment is to demonstrate a low cost solution for very large...

PROSPECT is a reactor antineutrino experiment consisting of a segmented 6Li-loaded liquid scintillator antineutrino detector designed to probe short-baseline neutrino oscillations and precisely measure the reactor antineutrino spectrum. The experiment will be located at the High Flux Isotope Reactor (HFIR) at Oak Ridge National Lab. The three ton detector will be located 7-12 m from the...

The determination of the Majorana nature of the neutrino is the chief goal of the proposed next generation of neutrinoless double-beta decay (0νββ) experiments. By achieving a sensitivity on the rate of 0νββ in 136Xe of 1.9 × 1025 years, the predecessor to nEXO, EXO-200, has demonstrated the feasibility of using 136Xe for potentially observing neutrinoless double-beta decay. Building on the...

MicroBooNE is a liquid argon Time Projection Chamber (TPC) located in the Booster Neutrino Beam at Fermilab. One of its main goals is to study the >3σ excess observed at low energy (Eν ~ 200-600 MeV) by the MiniBooNE experiment, which was located in the same beam.
Two independent analyses are ongoing in MicroBooNE to study this possible excess.
One of them uses Deep Learning...

In this talk, I will discuss leptonic unitarity violation at energy scale much lower than the electroweak scale in neutrino oscillation phenomena. The main features which distinguish it from high scale unitarity violation are preservation of lepton flavor universality and absence of zero-distance neutrino flavor transition. For concreteness, we work in the framework of 3 active plus N sterile...

CUORE (Cryogenic Underground Observatory for Rare Events) is an array of 988 TeO2 bolometers arranged in 19 towers with a total active mass of 742 kg located at the Laboratori Nazionali del Gran Sasso (LNGS) in Italy. The primary purpose of CUORE is to search for the neutrinoless double beta decay of 130Te, which if observed, would establish the Majorana nature of neutrinos as well as...
