Measurements of Higgs Boson Properties using the ATLAS Detector

open access: yesEPJ Web of Conferences, 2014
Measurements are presented of the production properties, couplings and spin-parity of the recently discovered Higgs-like boson using the decays into boson pairs, γγ, ZZ∗→ 4ℓ and WW∗→ ℓνℓν.

The Huang–Yang Formula for the Low‐Density Fermi Gas: Upper Bound

open access: yesCommunications on Pure and Applied Mathematics, Volume 79, Issue 8, Page 1919-1972, August 2026.
ABSTRACT We study the ground state energy of a gas of spin 1/2$1/2$ fermions with repulsive short‐range interactions. We derive an upper bound that agrees, at low density ϱ$\varrho$, with the Huang–Yang conjecture. The latter captures the first three terms in an asymptotic low‐density expansion, and in particular the Huang–Yang correction term of order

Quark-universal U(1) breaking scalar at the LHC

open access: yesJournal of High Energy Physics
If the quarks or leptons are charged under a new U(1) gauge symmetry, then besides a Z′ boson there must exist at least one new boson whose decay products include Standard Model particles. In the case of a minimal symmetry breaking sector, that new boson

The sensitivity of the Higgs boson branching ratios to the W boson width

open access: yesPhysics Letters B, 2016
The Higgs boson branching ratio into vector bosons is sensitive to the decay widths of those vector bosons because they are produced with at least one boson significantly off-shell.

Loop Quantum Photonic Chip for Coherent Multi‐Time‐Step Evolution

open access: yesLaser &Photonics Reviews, Volume 20, Issue 16, 21 August 2026.
A loop quantum photonic chip (Loop‐QPC) enabling efficient multi‐step quantum simulation in a single run is demonstrated. Combining recirculating loops with cycle‐or‐measure control, Loop‐QPC eliminates repeated reprogramming and reduces loss. Experimental demonstration of three‐step unitary evolution confirms high‐fidelity operation, showcasing the ...

Chiral bosonization as a duality [PDF]

open access: yesPhysical Review D, 1996
We demonstrate that the technique of abelian bosonization through duality transformations can be extended to gauging anomalous symmetries. The example of a Dirac fermion theory is first illustrated. This idea is then also applied to bosonize a chiral fermion by gauging its chiral phase symmetry.

Local Structural Signatures of Shear Bands in Metallic Glasses via Electron Nanodiffraction

open access: yesSmall Methods, Volume 10, Issue 15, 7 August 2026.
In this research, we employed scanning electron nano‐diffraction to investigate the local degree of centrosymmetry and structural anisotropy (strain) in deformed metallic glass. The study provides significant new insights into the deformation mechanisms of glassy materials, revealing the nature of local structural transformations and demonstrating how ...

Search for heavy resonances in final states with four leptons and missing transverse momentum or jets in pp collisions at s $$ \sqrt{s} $$ = 13 TeV with the ATLAS detector

open access: yesJournal of High Energy Physics
A search for a new heavy boson produced via gluon-fusion in the four-lepton channel with missing transverse momentum or jets is performed. The search uses proton-proton collision data equivalent to an integrated luminosity of 139 fb −1 at a centre-of ...

Rheology and Structure of Fe‐Mg‐Ca Enriched Silicate Melt: Benchmarking Viscosity Models for an Exotic Planetary Composition

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 8, August 2026.
Abstract Silicate melt viscosity plays a pivotal role in the evolution of rocky bodies within the Solar System, exerting first‐order control on mantle differentiation and stratification, while dictating the metal‐silicate separation and the subsequent volcanic activity.

On the feasibility of a 750 GeV complementary Higgs boson

open access: yesResults in Physics, 2016
Summary: It is shown that the adoption of the Stueckelberg mechanism, as an alternative to the Spontaneous Symmetry Breaking mechanism, gives an adequate explanation for the recent reported signatures in LHC experiments at CERN, which points to the ...
