Multi-Higgs Boson Production with Anomalous Interactions at Current and Future Proton Colliders

Andreas Papaefstathiou, Gilberto Tetlalmatzi-Xolocotzi

We investigate multi-Higgs boson production at proton colliders, in a framework involving anomalous interactions, focusing on triple Higgs boson production. We consider modificatio…

Tensions in $e^{+} e^{-} \to π^{+} π^{-} (γ)$ measurements: the new landscape of data-driven hadronic vacuum polarization predictions for the muon $g - 2$

M. Davier, A. Hoecker, A. M. Lutz +2

The situation of the experimental data used in the dispersive evaluation of the hadronic vacuum polarization contribution to the anomalous magnetic moment of the muon is assessed i…

Kicking it Off(-shell) with Direct Diffusion

Anja Butter, Tomas Jezo, Michael Klasen +3

Off-shell effects in large LHC backgrounds are crucial for precision predictions and, at the same time, challenging to simulate. We present a novel method to transform high-dimensi…

Precision-Machine Learning for the Matrix Element Method

Theo Heimel, Nathan Huetsch, Ramon Winterhalder +2

The matrix element method is the LHC inference method of choice for limited statistics. We present a dedicated machine learning framework, based on efficient phase-space integratio…

Phase space of electron- and muon-neutrino and antineutrino scattering off nuclei

M. Martini, M. Ericson, G. Chanfray

We discuss the electron and muon neutrino and antineutrino double differential cross sections on carbon in the quasielastic as well as in the multinucleon and one pion production c…

Jet Diffusion versus JetGPT -- Modern Networks for the LHC

Anja Butter, Nathan Huetsch, Sofia Palacios Schweitzer +3

We introduce two diffusion models and an autoregressive transformer for LHC physics simulations. Bayesian versions allow us to control the networks and capture training uncertainti…

A search for neutron-to-hidden-neutron oscillations in a ultra-cold neutron beam

G. Ban, J. Chen, P. -J. Chiu +11

Models that postulate the existence of hidden sectors address contemporary questions, such as the source of baryogenesis and the nature of dark matter. Among the possible mixing pr…

The Euclidean Adler Function and its Interplay with $Δ α_{QED}^{had}$ and $α_{s}$

M. Davier, D. Díaz-Calderón, B. Malaescu +3

Three different approaches to precisely describe the Adler function in the Euclidean regime at around $2 GeVs$ are available: dispersion relations based on the hadronic…
