Phenomenological anatomy of top-quark FCNCs induced by a light scalar singlet
Journal of High Energy PhysicsScalar 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 (

Baryon electric charge correlation as QCD magnetometer [PDF]
EPJ Web of ConferencesThe detection of strong magnetic fields in peripheral heavy-ion collisions is crucial for observing effects such as the chiral magnetic effect but has proven exceptionally difficult.

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

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‐

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

The Purely Leptonic and Semileptonic Decays of Ds∗ Meson
Advances in High Energy Physics, Volume 2026, Issue 1, 2026.With the potential prospects of the Ds∗ at high‐luminosity heavy‐flavor experiments in the future, we investigated the CKM‐favored and tree‐dominated leptonic Ds∗⟶ℓν¯ℓ,ℓ=e,μ,τ and semileptonic Ds∗⟶Mℓ′ν¯ℓ′ M=ϕ,η′,K and ℓ′=e,μ weak decays in the standard model (SM).
