Constraints on effective field theories via quadruple-differential angular decay rates from $t$-channel single-top-quark production at $\sqrt{s}=13$ TeV with the ATLAS detector
Events with $t$-channel single top quarks are used to probe effective field theory operators in $\sqrt{s}=13$ TeV proton-proton collision data corresponding to 140 fb$^{-1}$ recorded by the ATLAS detector at the Large Hadron Collider. [...]

Holography of K-complexity: Switchbacks and Shockwaves / Ambrosini, Marco (U. Geneva (main)) ; Rabinovici, Eliezer (Hebrew U. ; CERN) ; Sonner, Julian (U. Geneva (main))
In this paper we study Krylov complexity in the presence of single and multiple operators in the DSSYK model, where we can use the analytical techniques coming from chord diagrammatics. [...]

Search for dijet resonances with data scouting in proton-proton collisions at $ \sqrt{s} = $ 13 TeV
A search is presented for narrow resonances, with a mass between 0.6 and 1.8 TeV, decaying to pairs of jets, in proton-proton collisions at $ \sqrt{s} = $ 13 TeV. [...]

Influence of an external static magnetic field on prebreakdown electron emission and heating / Koitermaa, Roni (U. Helsinki (main) ; Tartu U.) ; Toktaganova, Marzhan (U. Helsinki (main)) ; Kyritsakis, Andreas (Tartu U.) ; Tiirats, Tauno (Tartu U.) ; Grudiev, Alexej (CERN) ; Zadin, Veronika (Tartu U.) ; Djurabekova, Flyura (U. Helsinki (main))
High magnetic fields can increase the occurrence of vacuum arcing, suggesting that both electric and magnetic fields can play a role in the vacuum arcing process. [...]

High-energy photons from Gamma-Ray Bursts, but no neutrinos / De Rújula, A (CERN ; U. Autonoma, Madrid (main))
The Cannon-Ball model of Gamma-Ray Bursts and their afterglows--described in the text and in innumerable previous occasions--is extremely successful and predictive. [...]

SPARTA: Python-Based Automated Spectral Parameter Analysis and Assessment System for Resonance Tracking / Semiz, Kerem (CERN ; Unlisted, DE ; Berlin, Tech. U.)
Accurately determining resonance frequencies and quality factors (Q) is crucial in accelerator physics and radiofrequency engineering, as these factors have direct impacts on system design, operational stability, and research results. [...]

On the maximum compactness of neutron stars / Rezzolla, Luciano (Goethe U., Frankfurt (main) ; CERN ; Trinity Coll., Dublin) ; Ecker, Christian (Goethe U., Frankfurt (main))
The stellar compactness, that is, the dimensionless ratio between the mass and radius of a compact star, $\mathcal{C} := M/R$, plays a fundamental role in characterising the gravitational and nuclear-physics aspects of neutron stars. [...]

Clearing up the Strong $CP$ problem / Benabou, Joshua N. (LBL, Berkeley ; UC, Berkeley) ; Hook, Anson (Maryland U.) ; Manzari, Claudio Andrea (Princeton, Inst. Advanced Study) ; Murayama, Hitoshi (LBL, Berkeley ; UC, Berkeley ; U. Tokyo (main)) ; Safdi, Benjamin R. (LBL, Berkeley ; UC, Berkeley ; CERN)
The absence of a neutron electric dipole moment (EDM) constrains the quantum chromodynamics (QCD) theta angle to be less than one part in ten billion, posing the Strong $CP$ problem. [...]
