Charged-Lepton Flavour Physics

, 2012
This writeup of a talk at the 2011 Lepton-Photon symposium in Mumbai, India, summarises recent results in the charged-lepton flavour sector. I review searches for charged-lepton flavour violation, lepton electric dipole moments and flavour-conserving CP ...

The global geometrical property of jet events in high-energy nuclear collisions

European Physical Journal C: Particles and Fields, 2020
We present the first theoretical study of medium modifications of the global geometrical pattern, i.e., transverse sphericity ( $$S_{\perp }$$ S ⊥ ) distribution of jet events with parton energy loss in relativistic heavy-ion collisions.

TAU2012 Summary

, 2013
The main highlights discussed at TAU2012 are briefly summarized. Besides the standard topics on lepton physics covered also at previous conferences (universality, QCD tests, V_{us} determination from tau decay, g-2, neutrino oscillations, lepton-flavour ...

The Tau Lepton [PDF]

Annual Review of Nuclear and Particle Science, 1980
The author reviews the experimental knowledge of the properties of the tau lepton and the tau neutrino. The conventional theory of lepton properties and interactions is summarized; and that theory is compared with experiment. Future directions for research in tau and tau neutrino physics are described.

Phototransmutation of leptons [PDF]

Physical Review D, 2000
By photo-transmutation of leptons we mean photon-lepton reactions of the following type: $ l_ \longrightarrow l_ $ with $l_ \neq l_ $, occurring as a consequence of the lepton mass matrix changing its orientation (rotating) under changing scales. In this paper, we first discuss these reactions in general terms, then proceed to the calculation of

Extracting jet transport coefficient via single hadron and dihadron productions in high-energy heavy-ion collisions

European Physical Journal C: Particles and Fields, 2019
We study the suppressions of high transverse momentum single hadron and dihadron productions in high-energy heavy-ion collisions based on the framework of a next-to-leading-order perturbative QCD parton model combined with the higher-twist energy loss ...

Vector meson spectral function in a dynamical AdS/QCD model

European 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.

Lepton Mass Formula. [PDF]

Physical 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]

Physical 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

Characterizing the Signals and Backgrounds in a Low Earth Orbiting Cherenkov Detector, and Background Mitigation Strategies

Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.
Abstract Cherenkov detectors have been used in space for decades to measure Galactic Cosmic Rays (GCRs), Solar Energetic Particles (SEPs) and trapped particles. We present proof‐of‐concept GRAS/Geant4 simulations to both show that a cubic fused silica Cherenkov detector with SiPM in LEO has a good sensitivity to SEP and GCR protons as a function of cut‐
