Atomic Spectroscopy Probes of New Physics / Delaunay, Cédric (Annecy, LAPTH) ; Karr, Jean-Philippe (Paris, Lab. Kastler Brossel ; Paris U., VI-VII) ; Soreq, Yotam (Technion ; CERN)
Precision spectroscopy has long played a central role in testing the foundations of physics, from the early insights that led to the development of quantum mechanics to the validation of quantum electrodynamics and the determination of fundamental constants. [...]

Modified Abelian Gauge Theories / Dierigl, Markus (CERN) ; Minasian, Ruben (IPhT, Saclay ; IRFU, SPhN, Saclay) ; Novičić, Dušan (Munich, Max Planck Inst.)
The topological properties of field configurations in gauge theory contain important data about the (generalized) global symmetries of the theory as well as potential inconsistencies in the form of gauge anomalies. [...]

Enhanced Cosmic-Ray Antinuclei Fluxes with Dark Matter Annihilation into SUEPs / Di Mauro, Mattia (INFN, Turin) ; Gemmell, Caleb (Wisconsin U., Madison ; Toronto U.) ; Batz, Austin (Oregon U. ; LBL, Berkeley) ; Curtin, David (Toronto U.) ; Donato, Fiorenza (INFN, Turin) ; Fornengo, Nicolao (INFN, Turin) ; Kribs, Graham D. (Oregon U. ; CERN)
Standard-Model (SM) hadronic parton showers initiated by secondary cosmic-ray production or dark matter (DM) annihilations robustly predict very low antinuclei yields and a strong additional suppression for heavier antinuclei. [...]

The Dark Side of the Moon: Listening to Scalar-Induced Gravitational Waves / Blas, D. (Barcelona, IFAE ; ICREA, Barcelona) ; Foster, J.W. (Wisconsin U., Madison) ; Gouttenoire, Y. (U. Mainz, PRISMA ; Paris, Inst. Astrophys.) ; Iovino, A.J. (New York U., Abu Dhabi) ; Musco, I. (Nova Gorica U.) ; Trifinopoulos, S. (CERN ; Zurich U.) ; Vanvlasselaer, M. (U. Barcelona (main))
The collapse of large-amplitude primordial curvature perturbations into planetary-mass primordial black holes generates a scalar-induced gravitational wave background in the $μ$Hz frequency range that may be detectable by future Lunar Laser Ranging and Satellite Laser Ranging data. [...]

Precise QCD Predictions for Hadron-in-jet Production in $e^+e^-$ Collisions / Bonino, Leonardo (Zurich U.) ; Gehrmann-De Ridder, Aude (Zurich U. ; Zurich, ETH) ; Gehrmann, Thomas ; Huss, Alexander (Zurich U. ; CERN) ; Merlotti, Francesco (Zurich, ETH) ; Stagnitto, Giovanni (Genoa U.)
The production of identified hadrons inside jets in $e^+ e^-$ annihilation allows for detailed studies of parton-to-hadron fragmentation functions in a clean environment. [...]

Dark Matter from Eternity / Franciolini, G. (U. Padua (main) ; INFN, Padua ; CERN) ; Peloso, M. (U. Padua (main) ; INFN, Padua) ; Riotto, A. (U. Geneva (main))
We propose that the totality of dark matter in the universe might ascribe its origin to one of the key properties of cosmological inflation, that it may be eternal: regions that at the end of the primordial accelerated expansion of the universe never reheated, but keep eternally inflating, manifest themselves as primordial black holes in our observable universe.

Heavy-quark production in deep-inelastic scattering -- Mellin moments of structure functions / Klann, Marco (Hamburg U., Inst. Theor. Phys. II) ; Moch, Sven-Olaf (Hamburg U., Inst. Theor. Phys. II) ; Schönwald, Kay (CERN)
We compute Mellin moments of the heavy-quark structure functions in deep-inelastic scattering at next-to-leading order in quantum chromodynamics, retaining their full dependence on the heavy-quark mass. [...]
