Deeper understanding of neutrino neutral current elastic interaction is desired for improving sensitivity in search for supernova relic neutrinos at Super-Kamiokande. Measuring the interaction with the T2K beam is a effective way, however, currently large systematic errors remain due to a poor model to describe neutron-oxygen reactions. To improve the current model, external experiments...

MicroBooNE is a 170-ton liquid argon time projection chamber located in the Booster neutrino beam at Fermilab. Recently, the MicroBooNE collaboration produced its first measurements of neutrino scattering on argon, a key step toward the experiment’s goals of clarifying neutrino-nucleus interactions and explaining the anomalous excess of electron neutrino-like events seen in MiniBooNE. We...

The Reactor Experiment for Neutrino Oscillation (RENO) has been taking data from August, 2011 using the two identical near and far detectors at Hanbit Nuclear Power Plant in Korea. The neutrino mixing angle θ13 and the squared mass difference Δm2ee have been successfully measured by observing the energy dependent disappearance of reactor antineutrinos tagged by neutron capture by gadolinium....

New physics signals with displaced vertices have attracted the recent attention of the collider community (theoretical and experimental). In this talk, we will describe how a model of non-sterile right-handed neutrinos with masses being proportional to the electroweak scale (~246 GeV) naturally gives rise to long-lived particles with displaced vertices as characteristic signals. An interesting...

Recent re-evaluations of antineutrino spectrum emitted by nuclear reactor have led to the observation of a ~7% deficit in neutrino flux at short distance from reactors with respect to predictions. This deficit, known as the Reactor Antineutrino Anomaly (RAA), could be the signature of an oscillation of antineutrino towards a light sterile neutrino with a mass scale of 1eV. However, it is not...

Ultrahigh energy (UHE) neutrinos may serve as important messengers that give us useful information about the origin of the Universe. Knowledge of UHE neutrino interaction cross sections is a necessary ingredient in any UHE neutrino measurement. A study of UHE neutrino-nucleon cross sections would also allow us to explore strong interactions at incredibly high energies. In this talk, I review...

The violation of Lorentz invariance is predicted by most of the theories beyond the Standard Model as string theories or quantum loop gravities. It arises as a consequence of merging the Standard Model with gravity, whose effects appear at the Planck mass scale. Therefore, the observation of the violation of Lorentz invariance (and CPT invariance) is searched as a very strong hint of physics...

We explain why determining whether neutrinos are Majorana particles, identical to their antiparticles, or Dirac particles, distinct from their antiparticles, is so challenging. We then discuss ways through which we can attempt to make this determination, including the primary approach, which is the search for neutrinoless double beta decay, and several alternative approaches.
