Classical and quantum physics mix [PDF]

open access: yesNature, 1995
A neat way of talking of quantum and classical physics in the same language will be of interest in itself even if it does not avoid the need for a quantum theory of gravity; but that would be a huge extra.

Physical range of majorana neutrino mixing parameters [PDF]

open access: yesPhysical Review D, 2008
If neutrinos are Majorana fermions, the lepton mixing parameter space consists of six mixing parameters: three mixing angles and three CP-odd phases. A related issue concerns the physical range of the mixing parameters. What values should these take so that all physically distinguishable mixing scenarios are realized?

Spectrally resolved wave-mixing between near- and far-infrared pulses in gas [PDF]

open access: yes, 2013
We investigate the nonlinear wave-mixing in gases between intense, short optical pulses and long-wavelength fields (mid infrared and terahertz). We show numerically that the beating between the sum- and difference-frequency generation components can be ...

Theoretical and Phenomenological Status of Neutrino Physics: A Brief Review

open access: yesAdvances in High Energy Physics, 2015
We present an overview of recent progress in the theoretical and phenomenological studies of neutrino masses, lepton avor mixing, and CP violation. Firstly, We discuss the status of neutrino mass with in the Standard Model (SM) of particle physics.

Lepton masses and mixing from modular S4 symmetry [PDF]

open access: yesNuclear Physics B, 2018
We study models of lepton masses and mixing based on broken modular invariance. We consider invariance under the finite modular group Γ 4 ≃ S 4 and focus on the minimal scenario where the expectation value of the modulus is the only source of symmetry ...

Chemical element transport in stellar evolution models [PDF]

open access: yesRoyal Society Open Science, 2017
Stellar evolution computations provide the foundation of several methods applied to study the evolutionary properties of stars and stellar populations, both Galactic and extragalactic.

The ideal mixing departure in vector meson physics [PDF]

open access: yesThe European Physical Journal C, 2003
In this work we study the departure for the ideal $ϕ-ω$ mixing angle in the frame of the Nambu-Jona-Lasinio model. We have shown that in that context, the flavour symmetry breaking is unable to produce the shifting in the mixing angle. We introduce a nonet symmetry breaking in the neutral vector sector to regulate the non-strange content of the $ϕ ...

Prospects for beyond the Standard Model physics searches at the Deep Underground Neutrino Experiment [PDF]

open access: yesEuropean Physical Journal C: Particles and Fields, 2020
The Deep Underground Neutrino Experiment (DUNE) will be a powerful tool for a variety of physics topics. The high-intensity proton beams provide a large neutrino flux, sampled by a near detector system consisting of a combination of capable precision ...

Trimaximal neutrino mixing from modular A4 invariance with residual symmetries [PDF]

open access: yesPhysics Letters B, 2018
We construct phenomenologically viable models of lepton masses and mixing based on modular A 4 invariance broken to residual symmetries Z 3 T or Z 3 S T and Z 2 S respectively in the charged lepton and neutrino sectors.

The Nature of Massive Neutrinos

open access: yesAdvances in High Energy Physics, 2013
The compelling experimental evidences for oscillations of solar, reactor, atmospheric, and accelerator neutrinos imply the existence of 3-neutrino mixing in the weak charged lepton current.
