Single-wave solutions of the neutrino fast flavor system. Part II. Weak instabilities and their resonant behavior

Journal of High Energy Physics
Flavor instabilities in dense neutrino media trigger exponential growth of flavor waves, yet their nonlinear saturation remains poorly understood. We examine a simple proxy for this effect in the form of a single-wave solution of an axially symmetric ...

A radiatively induced neutrino mass model with hidden local U(1) and LFV processes ℓ i → ℓ j γ, μ → eZ′ and μe → ee

Journal of High Energy Physics, 2021
We investigate a model based on hidden U(1) X gauge symmetry in which neutrino mass is induced at one-loop level by effects of interactions among particles in hidden sector and the Standard Model leptons.

Gravitational Radiation From Binary Systems With Time Varying Masses

Annalen der Physik, Volume 538, Issue 8, August 2026.
We extend the standard approach pioneered in the works by Peters and Mathews to include the mass loss processes of the binary components, by obtaining the variations due to gravitational radiation of the main physical parameters. As an application of our results we consider gravitational radiation emission in binary magnetar systems.

Superluminal velocity through near-maximal neutrino oscillations or by being off shell

, 2012
Recently it was suggested that the observation of superluminal neutrinos by the OPERA collaboration may be due to group velocity effects resulting from close-to-maximal oscillation between neutrino mass eigenstates, in analogy to known effects in optics.

Neutrino oscillations at high densities: cosmological and astrophysical aspects [PDF]

, 2011
This doctoral thesis treats the effects of neutrino oscillations in the early universe and supernovae. The main probe for the context of the early universe is big bang nucleosynthesis (BBN).

A LENS on DUNE-PRISM: characterizing a neutrino beam with off-axis measurements

Journal of High Energy Physics
Upcoming precision long-baseline neutrino oscillation experiments will be severely limited by the large systematic uncertainties associated with neutrino flux predictions and neutrino-nucleus cross sections.

Flavor-dependent long-range neutrino interactions in DUNE & T2HK: alone they constrain, together they discover

Journal of High Energy Physics, 2023
Discovering new neutrino interactions would represent evidence of physics beyond the Standard Model. We focus on new flavor-dependent long-range neutrino interactions mediated by ultra-light mediators, with masses below 10 −10 eV, introduced by new ...

Future Long-Baseline Neutrino Facilities and Detectors [PDF]

, 2013
We review the ongoing effort in the US, Japan, and Europe of the scientific community to study the location and the detectorperformance of the next-generation long-baseline neutrino facility.

Theory of neutrino slow flavor evolution. Part II. Space-time evolution of linear instabilities

Journal of High Energy Physics
Slow flavor evolution (defined as driven by neutrino masses and not necessarily “slow”) is receiving fresh attention in the context of compact astrophysical environments.

Curtailing the dark side in non-standard neutrino interactions

Journal of High Energy Physics, 2017
In presence of non-standard neutrino interactions the neutrino flavor evolution equation is affected by a degeneracy which leads to the so-called LMA-Dark solution.
