Constraining non-standard neutrino interactions with neutral current events at long-baseline oscillation experiments

Journal of High Energy Physics
We explore, for the first time, neutral-current events at long-baseline experiments to constrain vector and axial-vector neutrino non-standard interactions (NSI) with quarks. We leverage the flavor dependence of NSIs to perform an oscillation analysis in

Recent advances in neutrino astrophysics

, 2014
Neutrinos are produced by a variety of sources that comprise our Sun, explosive environments such as core-collapse supernovae, the Earth and the Early Universe. The precise origin of the recently discovered ultra-high energy neutrinos is to be determined

Synergy between DUNE and T2HKK to probe invisible neutrino decay

Journal of High Energy Physics
We address the consequence of invisible neutrino decay within the framework of two long base-line neutrino experiments: T2HKK (Tokai-to-Hyper-Kamiokande-to-Korea) and DUNE (Deep Underground Neutrino experiment).

Constraints on neutrino and dark radiation interactions using cosmological observations

, 2012
Observations of the cosmic microwave background (CMB) and large-scale structure (LSS) provide a unique opportunity to explore the fundamental properties of the constituents that compose the cosmic dark radiation background (CDRB), of which the three ...

Solar neutrinos and leptonic spin forces

Journal of High Energy Physics
We quantify the effects of light spin-zero particles with pseudoscalar couplings to leptons and scalar couplings to nucleons on the evolution of solar neutrinos. In this scenario the matter potential sourced by the nucleons in the Sun’s matter gives rise

Spin light of neutrino in astrophysical environments

, 2017
The ${\it {spin \ \ light \ \ of \ \ neutrino}}$ ($SL\nu$) is a new possible mechanism of electromagnetic radiation by a massive neutrino (with a nonzero magnetic moment) moving in media.

Double Froggatt--Nielsen Mechanism

, 2016
We present a doubly parametric extension of the standard Froggatt--Nielsen (FN) mechanism. As is well known, mass matrices of the up- and down-type quark sectors and the charged lepton sector in the standard model can be parametrized well by a parameter $

Neutrinoless double beta decay in light of JUNO first data

Journal of High Energy Physics
The first results from the JUNO reactor neutrino oscillation experiment improve our knowledge of neutrino masses and mixing parameters, especially the solar angle θ s ≡ θ 12 and the solar mass squared difference Δ m s 2 ≡ Δ m 21 2 $$ \Delta {m}_s^2\equiv

Majorana neutrinos and other Majorana particles:Theory and experiment

, 2014
This is a somewhat modified version of Chapter 15 of the book "The Physics of Ettore Majorana", by Salvatore Esposito with contributions by Evgeny Akhmedov (Ch. 15) and Frank Wilczek (Ch.

Search for electromagnetic properties of the neutrino in $\gamma e$ and $\gamma\gamma$ collisions at CLIC

, 2012
We have examined nonstandard $\gamma\nu\bar\nu$ and $\gamma\gamma\nu\bar\nu$ couplings via $\nu\bar\nu$ production in a $e\gamma$ and $\gamma\gamma$ collisions at the CLIC.
