Scalar QED with Rydberg atoms
Yannick Meurice, James Corona, Sergio Cantu +6
We review recent suggestions to quantum simulate scalar electrodynamics (the lattice Abelian Higgs model) in dimensions with rectangular arrays of Rydberg atoms. We show that…
Non-Relativistic Quantum Chromodynamics in Parton Showers
Naomi Cooke, Philip Ilten, Leif Lönnblad +1
Measurements of quarkonia isolation in jets at the Large Hadron Collider (LHC) have been shown to disagree with fixed-order non-relativistic quantum chromodynamics (NRQCD) calculat…
Towards a data-driven model of hadronization using normalizing flows
Christian Bierlich, Phil Ilten, Tony Menzo +5
We introduce a model of hadronization based on invertible neural networks that faithfully reproduces a simplified version of the Lund string model for meson hadronization. Addition…
Rational Q-systems at Root of Unity I. Closed Chains
Jue Hou, Yunfeng Jiang, Yuan Miao
The solution of Bethe ansatz equations for XXZ spin chain with the parameter being a root of unity is infamously subtle. In this work, we develop the rational -system for th…
Matrix element corrections in the Pythia8 parton shower in the context of matched simulations at next-to-leading order
Stefano Frixione, Simone Amoroso, Stephen Mrenna
We discuss the role of matrix element corrections (MEC) to parton showers in the context of MC@NLO-type matchings for processes that feature unstable resonances, where MEC are liab…
Reweighting Monte Carlo Predictions and Automated Fragmentation Variations in Pythia 8
Christan Bierlich, Philip Ilten, Tony Menzo +5
This work reports on a method for uncertainty estimation in simulated collider-event predictions. The method is based on a Monte Carlo-veto algorithm, and extends previous work on…
