50 Years of Quantum Chromodynamics

Franz Gross, Eberhard Klempt, Stanley J. Brodsky +92

This paper presents a comprehensive review of both the theory and experimental successes of Quantum Chromodynamics, starting with its emergence as a well defined theory in 1972-73…

Note on the definitions of branching ratios of overlapping resonances

V. Burkert, V. Crede, E. Klempt +8

Branching ratios for the decay of hadrons with large width or near thresholds depend on their definition. We test different definitions and show that rather different branching rat…

First Evaluation of Meson and lepton Spectra and Search for Heavy Neutral Leptons at ILC Beam Dump

Mihoko M. Nojiri, Yasuihito Sakaki, Kohsaku Tobioka +1

A beam dump experiment can be seamlessly added to the {proposed} International Linear Collider (ILC) program because the high energy electron beam should be dumped after the collis…

SYMBA: Symbolic Computation of Squared Amplitudes in High Energy Physics with Machine Learning

Abdulhakim Alnuqaydan, Sergei Gleyzer, Harrison Prosper

The cross section is one of the most important physical quantities in high-energy physics and the most time consuming to compute. While machine learning has proven to be highly suc…

Impact of the recent measurements of the top-quark and W-boson masses on electroweak precision fits

J. de Blas, M. Pierini, L. Reina +1

We assess the impact of the very recent measurement of the top-quark mass by the CMS Collaboration on the fit of electroweak data in the Standard Model and beyond, with particular…

Computational challenges for multi-loop collider phenomenology

Fernando Febres Cordero, Andreas von Manteuffel, Tobias Neumann

Precision measurements at the LHC and future colliders require theory predictions with uncertainties at the percent level for many observables. Theory uncertainties due to the pert…

NLO QCD corrections to full off-shell production of including leptonic decays

Giuseppe Bevilacqua, Heribertus Bayu Hartanto, Manfred Kraus +2

Motivated by ongoing new physics searches in the top-quark sector at the Large Hadron Collider we report on the calculation of NLO QCD corrections to the Standard Model $pp\to t\ba…

Event Generators for High-Energy Physics Experiments

J. M. Campbell, M. Diefenthaler, T. J. Hobbs +209

We provide an overview of the status of Monte-Carlo event generators for high-energy particle physics. Guided by the experimental needs and requirements, we highlight areas of acti…

at the LHC: On the size of off-shell effects and prompt -jet identification

Giuseppe Bevilacqua, Huan-Yu Bi, Heribertus Bayu Hartanto +3

We investigate full off-shell effects in production in the dilepton channel at the LHC with the center-of-mass energy TeV. Specifically, we compu…

New Physics Searches at Kaon and Hyperon Factories

Evgueni Goudzovski, Diego Redigolo, Kohsaku Tobioka +61

Rare meson decays are among the most sensitive probes of both heavy and light new physics. Among them, new physics searches using kaons benefit from their small total decay widths…
