Neutrino physics from Cosmology [PDF]

, 2013
In recent years precision cosmology has become an increasingly powerful probe of particle physics. Perhaps the prime example of this is the very stringent cosmological upper bound on the neutrino mass.

Neutrino Observatories Can Characterize Cosmic Sources and Neutrino Properties [PDF]

Phys.Rev.D67:073024,2003, 2003
Neutrino telescopes that measure relative fluxes of ultrahigh-energy $\nu_{e}, \nu_{\mu}, \nu_{\tau}$ can give information about the location and characteristics of sources, about neutrino mixing, and can test for neutrino instability and for departures from CPT invariance in the neutrino sector.

Dynamical Pion Collapse and the Coherence of Conventional Neutrino Beams [PDF]

, 2015
In this paper we consider the coherence properties of neutrinos produced by the decays of pions in conventional neutrino beams. Using a multi-particle density matrix formalism we derive the oscillation probability for neutrinos emitted by a decaying pion

Progress in neutrino oscillation searches and their implications [PDF]

Pramana60:261-278,2003, 2003
Neutrino Oscillation, in which a given flavour of neutrino transforms into another is a powerful tool for probing small neutrino masses. The intrinsic neutrino properties involved are neutrino mass squared difference $\Delta m^2$ and the mixing angle in vacuum $\theta$.

Experimental tests for the Babu-Zee two-loop model of Majorana neutrino masses [PDF]

, 2006
The smallness of the observed neutrino masses might have a radiative origin. Here we revisit a specific two-loop model of neutrino mass, independently proposed by Babu and Zee.

The impact of neutrino-nucleus interaction modeling on new physics searches

Journal of High Energy Physics, 2022
Accurate neutrino-nucleus interaction modeling is an essential requirement for the success of the accelerator-based neutrino program. As no satisfactory description of cross sections exists, experiments tune neutrino-nucleus interactions to data to ...

Update on neutrino mixing in the early Universe [PDF]

, 2001
From the current cosmological observations of CMB and nuclear abundances we show, with an analytic procedure, that the total effective number of extra neutrino species $\Delta N_{\nu}^{\rm tot}< 0.3$.

Solar ν ¯ e $$ {\overline{\nu}}_e $$ flux: revisiting bounds on neutrino magnetic moments and solar magnetic field

Journal of High Energy Physics, 2022
The interaction of neutrino transition magnetic dipole moments with magnetic fields can give rise to the phenomenon of neutrino spin-flavour precession (SFP).

Global constraints on non-standard neutrino interactions with quarks and electrons

Journal of High Energy Physics, 2023
We derive new constraints on effective four-fermion neutrino non-standard interactions with both quarks and electrons. This is done through the global analysis of neutrino oscillation data and measurements of coherent elastic neutrino-nucleus scattering (

Physics with Beam Tau-Neutrino Appearance at DUNE [PDF]

, 2019
We explore the capabilities of the upcoming Deep Underground Neutrino Experiment (DUNE) to measure $\nu_\tau$ charged-current interactions and the associated oscillation probability $P(\nu_\mu \to \nu_\tau)$ at its far detector, concentrating on how such
