The Deep Underground Neutrino Experiment (DUNE) is an upcoming long baseline neutrino experiment. In addition to exploring the yet unknown parameters in the standard three flavor neutrino sector, an ancilliary goal of DUNE is to probe the subdominant effects induced by new physics such as a light eV-scale sterile neutrino. DUNE utilizes a wide band beam and provides us with an opportunity to...
Axions and dark photons are common in many extensions of the Standard Model. The dark axion portal—an axion coupling to the dark photon and photon—can significantly modify their phenomenology. We study the cosmological constraints on the dark axion portal from Cosmic Microwave Background (CMB) bounds on the energy density of dark radiation, ΔNeff. By computing the axion-photon-dark...
We focus on the potential of neutrino - 13C neutral current interactions in clarifying the reactor antineutrino flux around the 6 MeV region. The interactions produce 3.685 MeV photon line via the process of de-excitation of 13C in organic liquid scintillators, which can be observed in reactor neutrino experiments. We expect the future measurements of neutrino - 13C cross section in JUNO and...
We study the expected sensitivity to the mixing between sterile and tau neutrinos directly from the tau neutrino disappearance in the high-energy fixed target experiment. Here, the beam energy is large enough to produce tau neutrinos at the target with large luminosity. During their propagation to the detector, the tau neutrino may oscillate into sterile neutrino. By examining the energy...
We review the physics at the SND@LHC and its recent achievements.
Heavy Neutral Leptons (HNL) are a compelling target for discovery searches at accelerator experiments. The GENIE BeamHNL module is an experiment-agnostic, configurable simulation of HNL produced in the decays of particles that are made in neutrino beamlines. Applicable to HNL with mass less than the kaon's mass, BeamHNL produces a detailed record of decay events in an arbitrarily complex...
