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?

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.

Neutrinos in a Minimal 3-3-1 Model

open access: yesFrontiers in Physics, 2022
In this work, we present a general review of neutrino physics in the minimal 331 model. New gauge and scalar interactions are present, with violation of both flavor and lepton numbers.

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.

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 ...

Physics Concepts in Traditional Bakpia Production: Exploring Local Culinary Processes as Contextual Learning Resources

open access: yesPendipa
Traditional culinary practices often involve physics processes that can be interpreted through scientific principles, yet these phenomena are rarely explored as contextual learning resources in physics education.

Improved sensitivities of ESSνSB from a two-detector fit

open access: yesJournal of High Energy Physics, 2023
We discuss the improvement of the sensitivity of ESSνSB to the discovery of CP violation and to new neutrino physics which can be obtained with a two-detector fit of the data of the near and far detectors. In particular, we consider neutrino non-standard

The Role of Hematopoietic Cell Transplantation in Ataxia‐Telangiectasia

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Ataxia‐telangiectasia (A‐T) is a DNA repair disorder characterized by neurodegeneration, immunodeficiency, and cancer predisposition. Hematopoietic cell transplantation (HCT) is an established therapy in related disorders such as Fanconi anemia (FA) and Nijmegen breakage syndrome (NBS), but its role in A‐T is unclear.
