Implementation of supersymmetric processes in the HERWIG event generator [PDF]

, 2002
We describe the implementation of supersymmetric processes in the HERWIG Monte Carlo event generator. We define relevant parameter and mixing conventions and list the hard scattering matrix elements.

Probing new physics in class-I B-meson decays into heavy-light final states

Journal of High Energy Physics, 2021
With updated experimental data and improved theoretical calculations, several significant deviations are being observed between the Standard Model predictions and the experimental measurements of the branching ratios of B ¯ s 0 → D s ∗ + L ...

3D structure of jet-induced diffusion wake [PDF]

EPJ Web of Conferences
Jet-induced diffusion wake in heavy-ion collisions has a unique 3D structure as manifested in the jet-hadron correlations in rapidity and azimuthal angle.

New leptons and old lepton numbers

Nuclear Physics B, 1976
Abstract We discuss, within the framework of SU(2) × U(1) gauge theories, possible relationships between the new leptons and the old ones. The importance of the radiative decays U− → e−γ and U− → μ−γ in experimentally determining these relationships is stressed.

Power-aligned 2HDM: a correlative perspective on (g − 2) e,μ

Journal of High Energy Physics, 2021
With the hypothesis of minimal flavor violation, we find that there exists a power-aligned relation between the Yukawa couplings of the two scalar doublets in the two-Higgs-doublet model with Hermitian Yukawa matrices.

Leptonic Scalars versus Scalar Leptons [PDF]

Proceedings of Corfu Summer Institute 2019 "School and Workshops on Elementary Particle Physics and Gravity" — PoS(CORFU2019), 2020
The notion of scalars having lepton number, i.e. leptonic scalars, is discussed without supersymmetry, where scalar leptons reside. It is shown how dark parity comes from lepton parity, as well as its possible origin from grand unification. Two specific phenomenological applications to dark matter are described.

HFAG tau lepton averages

, 2014
The HFAG-Tau group has computed the world averages of the tau lepton properties using the experimental results available in early 2012. The tau lepton branching fractions, mass and lifetime are used to test lepton universality for charged weak currents ...

Lepton PDFs and multipurpose single-lepton searches at the LHC

Physical Review D, 2023
A final state consisting of one charged lepton, at least one jet, and little missing transverse energy can be a very promising signature of new physics at the LHC across a wide range of models. However, it has received only limited attention so far. In this work we discuss the potential sensitivity of this channel to various new physics scenarios.
