Lepton Mass Formula. [PDF]

open access: yesPhysical Review Letters, 1979
A recently proposed mass formula for the muon is extended to $\ensuremath{\tau}$ and other heavy leptons. It is postulated that a quantized magnetic self-energy of magnitude $\frac{3}{2}{\ensuremath{\alpha}}^{\ensuremath{-}1}{n}^{4}{M}_{e}$, where $n$ is a new quantum number, be added to the rest mass of a lepton to get the next heavy lepton in the ...

Lepton-number-violating four-body tau lepton decays [PDF]

open access: yesPhysical Review D, 2012
We study the four-body tau^+- -> nu_tau l^+- l^+- X^-+ decays where l=e or mu and X=pi, K, rho and K^* mesons. These decay processes violate the total lepton number (|Delta L|=2) and can be induced by the exchange of Majorana neutrinos. We consider an scenario where these decays are dominated by the exchange of only one heavy neutrino which produces

A Superalgebra Within: Representations of Lightest Standard Model Particles Form a Z25$\mathbb {Z}_2^5$‐Graded Algebra

open access: yesAnnalen der Physik, Volume 537, Issue 12, December 2025.
 A set of particle representations, familiar from the Standard Model, collectively form a superalgebra. Those representations mirroring the behaviour of the Standard Model's gauge bosons, and three generations of fermions, are each included in this algebra, with exception only to those representations involving the top quark.

RD*,RK* $$ {R}_{D^{\left(*\right)}},{R}_{K^{\left(*\right)}} $$ and neutrino mass in the 2HDM-III with right-handed neutrinos

open access: yesJournal of High Energy Physics, 2018
Given that the two-Higgs-doublet model of type III (2HDM-III) has the potential to address the RD* $$ {R}_{D^{\left(*\right)}} $$ anomalies while the resolution to the RK* $$ {R}_{K^{\left(*\right)}} $$ deficits requires new degrees of freedom within ...

Vector meson spectral function in a dynamical AdS/QCD model

open access: yesEuropean Physical Journal C: Particles and Fields, 2022
By using gauge/gravity duality, we calculate the spectral function of the heavy vector mesons with the presence of an intense magnetic field in a hot and dense medium.

Unified Parametrization of Quark and Lepton Mixing Matrices

open access: yes, 2005
We present a unified parametrization of quark and lepton mixing matrices. By using some simple relations between the mixing angles of quarks and leptons, i.e., the quark-lepton complementarity, we parametrize the lepton mixing matrix with the Wolfenstein

Leptonic decays of the tau lepton [PDF]

open access: yesEPJ Web of Conferences, 2019
In these proceedings we review the SM prediction for the tau leptonic decays, including the radiative $ (\tau \to \ell \lambda \nu \bar \nu ) $ and the five-body $ (\tau \to \ell \ell '\ell '\nu \bar \nu ) $ decay modes, which are among the most powerful tools to study precisely the structure of the weak interaction and to constrain possible ...

Transcriptomic Diversity of Pediatric Acute Myeloid Leukemia Genetic Drivers Correlates With Clinical Outcome and Expression of Stemness‐Related Genes

open access: yesCancer Medicine, Volume 14, Issue 21, November 2025.
ABSTRACT Background Pediatric acute myeloid leukemia (pAML) is comprised of a diverse set of oncogenic drivers (ODs) that have been risk‐stratified to inform prognosis and therapeutic decision‐making. Despite proteomic, transcriptomic, genetic, and epigenetic characterization of the pAML landscape, questions still remain about why certain ODs have ...

The decomposition of neutron-antineutron oscillation operators

open access: yesJournal of High Energy Physics, 2023
We study the systematic decomposition of the dimension nine neutron-antineutron oscillation operators at tree and one-loop levels. We discuss the topologies’ generation and the assignment of the chiral quarks.

A Note on the Connection between Non-Additive Entropy and h-Derivative

open access: yesEntropy, 2023
In order to study as a whole a wide part of entropy measures, we introduce a two-parameter non-extensive entropic form with respect to the h-derivative, which generalizes the conventional Newton–Leibniz calculus.
