The Simplest Dark Matter Model at the Edge of Perturbativity / Escudero, Miguel ; Hambye, Thomas
Increasingly sensitive direct detection dark matter experiments are testing important regions of parameter space for WIMP dark matter and pushing many models to the multi-TeV regime. [...]

Gravitational Wave Memory of Primordial Black Hole Mergers / Gasparotto, Silvia (Barcelona, IFAE) ; Franciolini, Gabriele (CERN) ; Domcke, Valerie (CERN)
The gravitational wave signal of binary compact objects has two main contributions at frequencies below the characteristic merger frequency: the gravitational wave signal associated with the early inspiral stage of the binary and the non-linear gravitational wave memory. [...]

Starlight from JWST: Implications for star formation and dark matter models / Ellis, John ; Fairbairn, Malcolm ; Urrutia, Juan ; Vaskonen, Ville
We confront the star formation rate in different dark matter (DM) models with UV luminosity data from JWST up to $z\simeq25$ and legacy data from HST. [...]

Renormalizing Two-Fermion Operators in the SMEFT via Supergeometry / Assi, Benoît (Fermilab ; Cincinnati U.) ; Helset, Andreas (CERN) ; Pagès, Julie (UC, San Diego) ; Shen, Chia-Hsien (Taiwan, Natl. Taiwan U. ; NCTS, Taipei)
We extend the geometric framework of field-space covariance for loop computations, thereby unifying the treatment of scalars, fermions, and gauge bosons in effective field theories. [...]

Long distance contributions to neutral $D$-meson mixing from lattice QCD / Di Carlo, Matteo (CERN) ; Erben, Felix (CERN) ; Hansen, Maxwell T. (Edinburgh U.)
The study of neutral $D$-meson mixing provides a unique probe of long-distance effects in the charm sector, where Standard Model contributions are dominated by nonperturbative effects. [...]

Natural complex plane for kaon CKM data: framework, status and future / Dery, Avital (CERN)
Kaon physics can be used to independently determine three out of the four parameters of the CKM matrix, without any B physics input. [...]

Probing CP-Violating Neutral Triple Gauge Couplings at Electron-Positron Colliders / Ellis, John (Shanghai Jiao Tong U. ; King's Coll. London ; CERN) ; He, Hong-Jian (Tsung-Dao Lee Inst., Shanghai ; Shanghai Jiao Tong U. ; Tsinghua U., Beijing ; Peking U., CHEP) ; Xiao, Rui-Qing (Peking U.)
We study the forms of CP-violating (CPV) neutral triple gauge couplings (nTGCs) that can be realized via dimension-8 operators in the Standard Model Effective Field Theory (SMEFT). [...]
