The strongest bounds on active-sterile neutrino mixing after Planck data
, 2013 Light sterile neutrinos can be excited by oscillations with active neutrinos in the early universe. Their properties can be constrained by their contribution as extra-radiation, parameterized in terms of the effective number of neutrino species N_ eff ...

Neutrino Properties and Tests of Symmetries [PDF]
, 2004 The fact that neutrinos have mass allows them to possess many other properties, like a magnetic dipole moment and a finite decay width. Theoretical expectations for these are, however, well beyond current experimental bounds, and the discovery of new exotic neutrino properties would indicate the presence of (more) new physics.

Recent Developments in Halide Perovskite Nanocrystals for Indirect X‐ray Detection
Advanced Materials Technologies, Volume 9, Issue 20, October 21, 2024.Perovskite nanocrystals act as scintillators under X‐ray illumination with different conversion yield, stability, or decay times and outperform commercial materials, depending on their composition, host matrix, and luminescence process. Besides the lead halide perovskites, there are lead‐free alternatives providing self‐trapped exciton emission ...

Neutrino Anisotropies after Planck
, 2013 We present new constraints on the rest-frame sound speed, c_{eff}^2, and the viscosity parameter, c_{vis}^2, of the Cosmic Neutrino Background from the recent measurements of the Cosmic Microwave Background anisotropies provided by the Planck satellite ...

Solar neutrinos and leptonic spin forces
Journal of High Energy PhysicsWe 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

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 ...

On the study of neutrino properties [PDF]
arXiv, 2005 We review the discovery of the neutrino and outline the history of neutrino physics. Many interesting phenomena involving the neutrino are exhibited. We also discuss the long-standing solar neutrino puzzle and the properties of the neutrino which lead to various important results. We present a possible experimental test of the neutrino property.

Synergy between DUNE and T2HKK to probe invisible neutrino decay
Journal of High Energy PhysicsWe 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).
