When the sterile neutrinos are subject to a protective symmetry, they can have masses around the electroweak scale and potentially large neutrino Yukawa couplings, which makes them testable at planned future particle colliders.

One of the main limiting factors in nu oscillation analysis is our understanding on the nu-nucleus scattering. In the particular case of a heavy nucleus, such as argon, we expect to be dominated by the nuclear structure modeling. MicroBooNE is a liquid argon time projection chamber located at 470 meters from the target of the Booster Neutrino Beam (BNB) which provides an almost pure NuMu beam, wit ... More

For the future large liquid scintillator detectors, given a typical galactic distance of 10 kpc and typical SN parameters, for instance the JUNO detector will register about 5000 events from the inverse beta decay (IBD), 2000 events from all-flavor elastic neutrino-proton scattering, as well as more than 300 events from neutrino-electron scattering, and the charge current and neutral current inter ...

One of the primary challenges in current and future precision neutrino oscillation measurements is understanding nuclear effects in neutrino-nucleus interactions. Current models are known to be deficient in a number of areas, leading to relatively large uncertainties which will become limiting soon. MicroBooNE is a liquid argon TPC in the booster neutrino beam at Fermilab, which has the ability to ... More

As neutrino oscillation experiments continue to improve their sensitivity, it is increasingly important to understand and constrain the details of neutrino interactions with complex nuclei. As part of this drive comes the desire to measure single pion production mechanisms, which can provide particular insight into the cross sections for neutrino interactions that induce baryon resonances and cohe ...

Liquid Argon Time Projection Chambers (LArTPCs) are sensitive to low energy electron neutrinos via a charged current interaction on argon. The Deep Underground Neutrino Experiment’s (DUNE’s) 40kt far detector at the Homestake mine in South Dakota will therefore offer a unique opportunity to study supernova neutrinos. The detection of galactic supernova burst neutrinos, a primary physics goal o ... More

The predictions of the cosmogenic-neutrino flux at 1e9 GeV are pretty solid and depend mostly on the composition of the cosmic-rays above 1e10 GeV. It is, therefore, no surprise that the hunt to detect the first cosmogenic neutrino is a hot topic in astroparticle physics. But pushing the experimental sensitivity into the predicted flux region is a challenge. A major obstacle for experiments is to ... More

The KArlsruhe TRItium Neutrino (KATRIN) experiment aims at the model-independent measurement of the electron neutrino mass. KATRIN is designed for a neutrino mass sensitivity of 0.2 eV (90\% CL) after three years of measurement time. In May 2018, KATRIN performed its First Tritium measurements. Along with the beta electrons, tritium beta decay creates ions inside the tritium source. The tritium io ... More

Neutrinos in the cosmic ray flux with energies above 100 PeV are detectable with the Surface Detector array (SD) of the Pierre Auger Observatory. Neutrino identification is efficiently done for neutrinos of all flavors interacting in the atmosphere at large zenith angles, as well as for Earth-skimming tau neutrinos. No neutrino candidates were found up to 31 Mar 2017, and this allowed to constrai ... More

A combined analysis of disappearance and appearance data of NOvA experiment gives three nearly degenerate solutions. This degeneracy can be understood by the following argument: We first consider $\nu_e$ appearance signal due to vacuum oscillations in the limit of maximal $\theta_{23}$ and no CP-violation. We then calculate the deviations induced in the signal event rate by (a) matter ef ... More

We show that neutral current (NC) measurements at neutrino detectors can play a valuable role in the search for new physics. Such measurements have certain intrinsic features and advantages that can fruitfully be combined with the usual well-studied charged lepton detection channels in order to probe the presence of new interactions or new light states. NC measurements provide access to different ... More
