A New Herwig7 Underlying Event Tune: from RHIC to LHC Energies

Autor: Qureshi, Umar Sohail, Elayavalli, Raghav Kunnawalkam, Mozarsky, Luke, Caines, Helen, Mooney, Isaac

We present parameter sets corresponding to new underlying event tunes for the Herwig7.3 Monte Carlo event generator. The existing Herwig tunes are in good agreement with LHC data, however, they are not typically designed for center-of-mass energies b

Mitigating Frequency Bias and Anisotropy in Language Model Pre-Training with Syntactic Smoothing

Autor: Martinez, Richard Diehl, Goriely, Zebulon, Caines, Andrew, Buttery, Paula, Beinborn, Lisa

Language models strongly rely on frequency information because they maximize the likelihood of tokens during pre-training. As a consequence, language models tend to not generalize well to tokens that are seldom seen during training. Moreover, maximum

Quadratic Optimal Control of Graphon Q-noise Linear Systems

Autor: Dunyak, Alex, Caines, Peter E.

The modelling of linear quadratic Gaussian optimal control problems on large complex networks is intractable computationally. Graphon theory provides an approach to overcome these issues by defining limit objects for infinite sequences of graphs perm

Deciphering yield modification of hadron-triggered semi-inclusive recoil jets in heavy-ion collisions

In relativistic heavy-ion collisions, a hot and dense state of matter, called the Quark-Gluon Plasma (QGP), is produced. Semi-inclusive jets recoiling from trigger hadrons of high transverse momenta ($p_{\mathrm{T}}$) can serve as an effective probe
