Hermitian Matrix Diagonalization and Its Symmetry Properties

open access: yesAdvances in High Energy Physics, Volume 2024, Issue 1, 2024.
A Hermitian matrix can be parametrized by a set consisting of its determinant and the eigenvalues of its submatrices. We established a group of equations which connect these variables with the mixing parameters of diagonalization. These equations are simple in structure and manifestly invariant in form under the symmetry operations of dilatation ...

Statistical Issues on the Neutrino Mass Hierarchy with Δχ2

open access: yesAdvances in High Energy Physics, Volume 2024, Issue 1, 2024.
The neutrino mass hierarchy determination (ν MHD) is one of the main goals of the major current and future neutrino experiments. The statistical analysis usually proceeds from a standard method, a single‐dimensional estimator (1D − Δχ2) that shows some drawbacks and concerns, together with a debatable strategy.

Higgs Information and NMSSM at the Large Hadron Collider

open access: yesAdvances in High Energy Physics, Volume 2024, Issue 1, 2024.
Information theory has proven to be a worthwhile tool for investigating the implications of the Higgs sector in the Next‐to‐Minimal Supersymmetric Standard Model (NMSSM) using Higgs information at the Large Hadron Collider (LHC) assessed through the entropy constructed by means of the branching ratios of decay channels of the Higgs boson.

The Absorptive Extra Dimensions

open access: yes, 2003
It is well known that gravity and neutrino oscillation can be used to probe large extra dimensions in a braneworld scenario. We argue that neutrino oscillation remains a useful probe even when the extra dimensions are small, because the brane-bulk ...

Neutrino oscillation physics with a Neutrino Factory [PDF]

open access: yesProceedings of XXIst International Europhysics Conference on High Energy Physics — PoS(EPS-HEP2011), 2012
We illustrate that the baseline Neutrino Factory configuration being developed within the International Design Study for the Neutrino Factory (the IDS-NF) is optimized for standard oscillation-physics measurements and for searches for new physics. For small values of θ13 (sin2 2θ13 < 10−2 ) a Neutrino Factory with two storage rings in which 25 GeV ...

Neutrino masses and oscillations

open access: yes, 2005
I summarize the status of three--neutrino oscillations that follow from combining the relevant world's data. The discussion includes the small parameters Delta_m-sol/Delta_m-atm and \sin^2\theta_{13}, which characterize the strength of CP violation in ...

Flavour-symmetric type-II Dirac neutrino seesaw mechanism

open access: yes, 2017
We propose a Standard Model extension with underlying A4 flavour symmetry where small Dirac neutrino masses arise from a Type-II seesaw mechanism. The model predicts the "golden" flavour-dependent bottom-tau mass relation, requires an inverted neutrino ...

Status of neutrino oscillations I: the three-neutrino scenario

open access: yes, 2003
We present a global analysis of neutrino oscillation data within the three-neutrino oscillation scheme, including in our fit all the current solar neutrino data, the reactor neutrino data from KamLAND and CHOOZ, the atmospheric neutrino data from Super ...
