Beyond Universality: Probing Lepton Flavor in the SMEFT
Cornelius Grunwald, Gudrun Hiller, Kevin Kröninger +1
We present a global analysis of lepton-flavor-specific operators in the Standard Model Effective Field Theory (SMEFT), combining data from collider and flavor physics experiments.…
ECFA Higgs, electroweak, and top Factory Study
H. Abidi, J. A. Aguilar-Saavedra, S. Airen +373
The ECFA Higgs, electroweak, and top Factory Study ran between 2021 and 2025 as a broad effort across the experimental and theoretical particle physics communities, bringing togeth…
Road map for the tuning of hadronic interaction models with accelerator-based and astroparticle data
Johannes Albrecht, Julia Becker Tjus, Noah Behling +52
In high-energy and astroparticle physics, event generators play an essential role, even in the simplest data analyses. As analysis techniques become more sophisticated, e.g. based…
Improving Air Shower Simulations by Tuning Pythia 8/Angantyr with Accelerator Data
Michael Windau, Chloé Gaudu, Karl-Heinz Kampert +1
We present a combined analysis of the Pythia 8 event generator using accelerator data and evaluate its impact on air shower observables. Reliable simulations with event generators…
Prompt and Conventional High-Energy Muon Spectra from a full Monte Carlo Simulation via
Ludwig Neste, Pascal Gutjahr, Mirco Hünnefeld +6
Extensive air showers produce high-energy muons that can be utilized to probe hadronic interaction models in cosmic ray interactions. Most muons originate from pion and kaon decays…
MCBench: A Benchmark Suite for Monte Carlo Sampling Algorithms
Zeyu Ding, Cornelius Grunwald, Katja Ickstadt +2
In this paper, we present MCBench, a benchmark suite designed to assess the quality of Monte Carlo (MC) samples. The benchmark suite enables quantitative comparisons of samples by…
