Gravireggeons in Extra Dimensions and Interaction of Ultra-high Energy Cosmic Neutrinos with Nucleons [PDF]

, 2003
We present the results on non-perturbative quantum gravity effects related to extra dimensions which can be comparable, in some cases, with the SM contributions, e.g. in lepton-lepton or lepton-nucleon scattering.

Analysis of carbohydrates and glycoconjugates by matrix‐assisted laser desorption/ionization mass spectrometry: An update for 2021–2022

Mass Spectrometry Reviews, Volume 44, Issue 3, Page 213-453, May/June 2025.
Abstract The use of matrix‐assisted laser desorption/ionization (MALDI) mass spectrometry for the analysis of carbohydrates and glycoconjugates is a well‐established technique and this review is the 12th update of the original article published in 1999 and brings coverage of the literature to the end of 2022.

Deciphering the Belle II data on B → Kν ν ¯ $$ B\to K\nu \overline{\nu} $$ decay in the (dark) SMEFT with minimal flavour violation

Journal of High Energy Physics
Recently, the Belle II collaboration announced the first measurement of the branching ratio B B + → K + ν ν ¯ $$ \mathcal{B}\left({B}^{+}\to {K}^{+}\nu \overline{\nu}\right) $$ , which is found to be about 2.7σ higher than the Standard Model (SM ...

Supersymmetric Lepton Flavor Violation [PDF]

AIP Conference Proceedings, 2010
We study a new supersymmetric mechanism for lepton flavor violation in a minimal extension of the MSSM with low-mass heavy singlet neutrinos, which is fully independent of the flavor structure of the soft SUSY breaking sector. We find that l -> l' gamma processes are forbidden in the SUSY limit, whilst the processes l -> l'l1 l2 and mu -> e ...

Modular S4 models of lepton masses and mixing [PDF]

Journal of High Energy Physics, 2018
We investigate models of charged lepton and neutrino masses and lepton mixing based on broken modular symmetry. The matter fields in these models are assumed to transform in irreducible representations of the finite modular group Γ4 ≃ S4.

Neutrinoloser Doppelbetazerfall: Der Gral der Neutrinophysik

Physik in unserer Zeit, Volume 56, Issue 3, Page 132-137, May 2025.
Die Entschlüsselung der Neutrinoeigenschaften ist auch siebzig Jahre nach ihrer Entdeckung noch nicht abgeschlossen. Es wäre eine spektakuläre Entdeckung, sollten Neutrinos ihre eigenen Antiteilchen sein und sich folglich als Majorana‐Teilchen entpuppen. Mehrere Experimente untersuchen diese Möglichkeit.

Phenomenological anatomy of top-quark FCNCs induced by a light scalar singlet

Journal of High Energy Physics
Scalar singlets under the Standard Model gauge group appear naturally in many well-motivated New Physics scenarios, such as the composite Higgs models. Unlike the Higgs boson in the Standard Model, they can induce large flavour-changing neutral currents (

The scalar unparticle effect on the charged lepton electric dipole moment

, 2007
We study the charged lepton electric dipole moment which is induced by the scalar unparticle mediation and we predict the appropriate range for the free parameters appearing in the effective lagrangian which drives the unparticle-standard model lepton ...

Electroweak Lepton-Lepton and Lepton-Antilepton Bound States

, 1999
In model independent way we consider the possibility of the existence of fermion-antifermion, fermion-fermion bound states which appear due to $ , Z^0(W^{\pm}$-bosons and scalar, pseudoscalars exchanges including radiative corrections. Our consideration includes the case where at least one particle in the bound state is Majorana fermion or scalar.This
