Search for charged-lepton-flavour violation in Z-boson decays with the ATLAS detector
, 2021 Leptons with essentially the same properties apart from their mass are grouped into three families (or flavours). The number of leptons of each flavour is conserved in interactions, but this is not imposed by fundamental principles. Since the formulation

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.

On Quark–Lepton Mixing and the Leptonic CP Violation
UniverseIn the absence of a Grand Unified Theory framework, connecting the values of the mixing parameters in the quark-and-lepton sector is a difficult task, unless one introduces ad hoc relations among the matrices that diagonalize such different kinds of fermions.

TRIPLICITY OF QUARKS AND LEPTONS [PDF]
Modern Physics Letters A, 2005 Quarks come in three colors and have electric charges in multiples of one-third. There are also three families of quarks and leptons. Though the first two properties can be understood in terms of unification symmetries such as SU(5), SO(10), or E6, why should there only be three families remains a mystery. We propose how all three properties involving

Insights into grand unified theories from current experimental data [PDF]
, 2015 In this thesis, we investigate several ways how the structure of a high energy particle physics model constituting a grand unification theory (GUT) in supersymmetry (SUSY) can be inferred from multiple types of information obtained at low energy ...

Search for anomalous production of prompt like-sign lepton pairs at s√=7TeV with the ATLAS detector [PDF]
, 2012 An inclusive search for anomalous production of two prompt, isolated leptons with the same electric charge is presented. The search is performed in a data sample corresponding to 4.7 fb−1 of integrated luminosity collected in 2011 at s√=7TeV with the ...

Drag force and heavy quark potential in a rotating background
Journal of High Energy PhysicsWe explored the gravity dual of a rotating quark-gluon plasma by transforming the boundary coordinates of the large black hole limit of Schwarchild-AdS5 metric.

The decomposition of neutron-antineutron oscillation operators
Journal 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.

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 $γ, Z^0(W^{\pm}$-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 ...

Heavy leptons, lepton mixing, and nonconservation of lepton-type number
Physics Letters B, 1977 Abstract Introducing a new weak doublet of heavy leptons, one is led to a mixing of the various lepton states with respect to the weak interaction and subsequently to the violation of electron and muon number conservation (e.g., the decay μ →e γ ). The new charged lepton can only decay via such a mixing and is therefore relatively long-lived ( τ >10
