Heavy Fermion Non-Decoupling Effects in Triple Gauge Boson Vertices
Within a spontaneously broken gauge group we carefully analyse and calculate triple gauge boson vertices dominated by triangle one-loop Feynman diagrams involving heavy fermions compared to external momenta and gauge boson masses.

Dark Matter, Baryon Asymmetry, and Spontaneous B and L Breaking [PDF]
We investigate the dark matter and the cosmological baryon asymmetry in a simple theory where baryon (B) and lepton (L) number are local gauge symmetries that are spontaneously broken.

Chemically Driven Nano‐Elastic Heterogeneities Control Fragility in Volcanic Melts
The study elucidates how nanoscale structural heterogeneity governs the mechanical behavior of volcanic glasses across compositions from basalt to rhyolite. Using a physicochemical framework, correlation length (ξ) and microscopic free volume (Vc) are derived from vibrational and physical properties, revealing systematic trends with silica content that

The SU(2)$_{D}$ lepton portals for muon g - 2, W boson mass and dark matter
We propose a novel model which extends the Standard Model (SM) by introducing a $SU(2)_D$ gauge symmetry. In this model, a dark $SU(2)_D$ Higgs doublet and a Higgs bi-doublet can contribute to the muon g-2 anomaly and the $W$ boson mass, remaining in ...

Topologically Protected Negative Entanglement
It is revealed that topological flat‐band edge states can lead to robust unconventional negative entanglement entropy scaling. This arises from a new mechanism of non‐Hermitian critical skin compression (nHCSC), which strongly “compresses” quantum information beyond flat‐band degeneracy.

Non-cancellation of electroweak logarithms in high-energy scattering
We study electroweak Sudakov corrections in high energy scattering, and the cancellation between real and virtual Sudakov corrections. Numerical results are given for the case of heavy quark production by gluon collisions involving the rates gg→tt¯,bb ...

Coordinate‐ and Spacetime‐Independent Quantum Physics
This article studies in the framework of quantum field theory in curved spacetime, if there exists a single zero‐rank‐tensor solution of a Klein‐Gordon PDE, being valid at once for the depicted spacetimes. The answer is shown to be affirmative, even for a class of such solutions having the standard applications in particle physics. ABSTRACT The concept

Higgsless models with fermions whose SU(2) properties are "ideally delocalized," such that the fermion's probability distribution is appropriately related to the W boson wavefunction, have been shown to minimize deviations in precision electroweak ...

Vortex Line Density in a Superfluid Turbulent Wake in the Zero Temperature Limit
The quasiclassical conjecture for quantum turbulence in a pure superfluid straightforwardly leads to the definition of the superfluid Reynolds number, Res=ud/κ$Re_s=ud/\kappa$, and suggests that the effective quantum viscosity should be of the order of the circulation quantum κ$\kappa$.
