Theory uncertainties of the irreducible background to VBF Higgs production / Chen, Xuan (Shandong U.) ; Ferrario Ravasio, Silvia (CERN) ; Haddad, Yacine (Northeastern U.) ; Höche, Stefan (Fermilab) ; Huston, Joey (Michigan State U.) ; Jezo, Tomas (Munster U., ITP) ; Liu, Jia-Sheng (Shandong U.) ; Preuss, Christian T. (Gottingen U.) ; Tarek, Ahmed (CERN) ; Winter, Jan (SUNY, Buffalo)
Higgs boson production through gluon fusion in association with two jets is an irreducible background to Higgs boson production through vector boson fusion, one of the most important channels for analyzing and understanding the Higgs boson properties at the Large Hadron Collider. [...]

Field-theoretic versus data-driven evaluations of electromagnetic corrections to hadronic vacuum polarization in $(g-2)_μ$ / Biloshytskyi, Volodymyr (Marseille, CPT ; Mainz U., Inst. Kernphys.) ; Erb, Dominik (U. Mainz, PRISMA) ; Meyer, Harvey B. (U. Mainz, PRISMA ; Helmholtz Inst., Mainz ; CERN) ; Parrino, Julian (Regensburg U.) ; Pascalutsa, Vladimir (Mainz U., Inst. Kernphys.)
The Standard Model prediction of the muon $g-2$ increasingly depends on lattice QCD computations of the hadronic vacuum polarization (HVP), where the isospin-breaking (IB) effects remain a significant source of uncertainty. [...]

Affleck-Dine Leptoflavorgenesis / Akita, Kensuke (Tokyo U.) ; Hamaguchi, Koichi (Tokyo U.) ; Ovchynnikov, Maksym (CERN)
We propose a scenario to produce large primordial lepton flavor asymmetries with vanishing total lepton asymmetry, based on the Affleck-Dine mechanism with Q-ball formation. [...]

Constraints on Dark Matter Models from Supermassive Black Hole Evolution / Ellis, John ; Fairbairn, Malcolm ; Urrutia, Juan ; Vaskonen, Ville
A semi-analytical model for the evolution of galaxies and supermassive black holes (SMBHs) within the $Λ$CDM paradigm has been shown to yield stellar mass-BH mass relations that reproduce both the JWST and pre-JWST observations. [...]

Chasing the two-Higgs-doublet model via electroweak corrections at $e^+e^-$ colliders / Bredt, Pia (Siegen U.) ; Banno, Tatsuya (KMI, Nagoya) ; Höfer, Marius (KIT, Karlsruhe, TP) ; Iguro, Syuhei (Nagoya U., IAR ; Nagoya U. ; KMI, Nagoya) ; Kilian, Wolfgang (Siegen U.) ; Ma, Yang (Louvain U., CP3) ; Reuter, Jürgen (DESY) ; Zhang, Hantian (CERN)
We present a comprehensive study of Higgs boson production associated with a neutrino pair at $e^+e^-$ colliders ($e^+ e^- \to h \, ν\barν$) at the next-to-leading-order accuracy in both the Standard Model and the two-Higgs-doublet model. [...]

Exploring Pintopia: Reflection Branes, Bordisms, and U-Dualities / Chakrabhavi, Vivek (Pennsylvania U.) ; Debray, Arun (U. Kentucky, Lexington) ; Dierigl, Markus (CERN) ; Heckman, Jonathan J. (Pennsylvania U.)
The U-dualities of maximally supersymmetric non-chiral supergravity (SUGRA) theories lead to strong constraints on the non-perturbative structure of quantum gravity. [...]

Axion lines from nuclear de-excitations in galactic stellar populations / Ning, Orion (UC, Berkeley ; LBL, Berkeley) ; Ray, Anupam (UC, Berkeley) ; Safdi, Benjamin R. (UC, Berkeley ; LBL, Berkeley ; CERN)
We show that mono-energetic axions are produced in abundance through nuclear de-excitations in nearby galaxies such as M87, which is the central galaxy of the Virgo cluster, and the starburst galaxy M82. [...]

Flow between extremal one-point energy correlators in QCD / Riembau, Marc (CERN ; EPFL, Lausanne, LPTP) ; Son, Minho (KAIST, Taejon)
The energy density generated by a vector current is characterized by a single parameter $a_{\mathcal{E}}$ bounded by unitarity to $-1/2 \leq a_{\mathcal{E}} \leq 1$, with extremal values saturated by free theories of different matter content. [...]

The modelling of the formation of colour-singlet hadrons from coloured partons, known as Hadronization, is crucial for generating realistic events in Monte Carlo Event Generators. [...]
