Out-of-Equilibrium Dynamics in a U(1) Lattice Gauge Theory via Local Information Flows: Scattering and String Breaking / Artiaco, Claudia ; Barata, João ; Rico, Enrique
We introduce local information flows as a diagnostic tool for characterizing out-of-equilibrium quantum dynamics in lattice gauge theories. [...]

Effects of Radiative Corrections on Starobinsky Inflation / Ellis, John (King's Coll. London ; CERN) ; Gherghetta, Tony (U. Minnesota, Minneapolis (main)) ; Kaneta, Kunio (Niigata U.) ; Ke, Wenqi (U. Minnesota, Minneapolis (main)) ; Olive, Keith A. (U. Minnesota, Minneapolis (main))
We analyze radiative corrections to the Starobinsky model of inflation arising from self-interactions of the inflaton, and from its Yukawa couplings, $y$, to matter fermions, and dimensionful trilinear couplings, $κ$, to scalar fields, which could be responsible for reheating the Universe after inflation.

HOPPET v2.0.0 release note / Karlberg, Alexander (CERN) ; Nason, Paolo (INFN, Milan Bicocca ; Milan Bicocca U. (main)) ; Salam, Gavin (U. Oxford (main)) ; Zanderighi, Giulia (Garching, Max Planck Inst. ; Munich, Tech. U.) ; Dreyer, Frédéric (Unlisted, US)
We document the three main new features in release 2.0.0 of the HOPPET parton distribution function evolution code, specifically support for N$^3$LO QCD evolution in the variable flavour number scheme, for the determination of hadronic structure functions for massless quarks up to N$^3$LO, and for QED evolution to an accuracy phenomenologically equivalent to NNLO QCD.

Correlation Function/Wilson Loop Duality in Gauge Theory from EFT / Chen, Hao (MIT, Cambridge, CTP) ; Monni, Pier Francesco (CERN) ; Pang, Zhaoyan (Peking U.) ; Vita, Gherardo (CERN) ; Zhu, Hua Xing (Peking U. ; Peking U., CHEP)
In this Letter, we initiate a systematic study of the $n$-point correlation functions (CF) in gauge theories in the sequential light-cone (SLC) limit. [...]

SymTFT Entanglement and Holographic (Non)-Factorization / Torres, Ethan (CERN) ; Yu, Xingyang (Virginia Tech., Blacksburg)
Given two otherwise decoupled $D$-dimensional CFTs which possess a common (finite) symmetry subcategory, one can consider entangled boundary states of their $(D+1)$-dimensional SymTFTs. [...]

Observables of boundary RG flows from string field theory / Scheinpflug, Jaroslav (Harvard U. (main)) ; Schnabl, Martin (Prague, Inst. Phys. ; CERN) ; Vošmera, Jakub (IPhT, Saclay)
We present simple explicit formulae for the change of the $g$-function, boundary state, boundary spectrum and structure constants between the endpoints of short boundary RG flows at next-to-leading order. [...]

Non-singlet vector current in lattice QCD: $\mathrm{O}(a)$-improvement from large volumes / Harris, Tim (ETH, Zurich (main)) ; Meyer, Harvey B. (CERN ; U. Mainz, PRISMA ; Helmholtz Inst., Mainz)
In previous work, we determined the improvement coefficients $c_\mathrm{V}$ and $c_{\tilde{\mathrm{V}}}$ required for the massless $\mathrm{O}(a)$-improvement of the local and point-split discretizations of the non-singlet vector current for $N_\mathrm{f}=3$ non-perturbatively $\mathrm{O}(a)$-improved Wilson fermions and the Lüscher-Weisz gauge action, using ensembles of large-volume configurations generated by the Coordinated Lattice Simulations (CLS) initiative.

Flavour, Accidentally / Banks, Hannah (Cambridge U. (main) ; New York U., CCPP) ; Crawford, Graeme (Glasgow U.) ; McCullough, Matthew (CERN) ; Sutherland, Dave (Glasgow U.)
We propose a new class of flavour models in which the spurion which breaks Standard Model flavour symmetries transforms in a non-minimal representation. [...]
