Using graph neural networks to reconstruct charged pion showers in the CMS High Granularity Calorimeter Open
A novel method to reconstruct the energy of hadronic showers in the CMS High Granularity Calorimeter (HGCAL) is presented. The HGCAL is a sampling calorimeter with very fine transverse and longitudinal granularity. The active media are sil…

Jet Flavour Tagging at FCC-ee with a Transformer-based Neural Network: DeepJetTransformer Open
Jet flavour tagging is crucial in experimental high-energy physics. A tagging algorithm, \texttt{DeepJetTransformer}, is presented, which exploits a transformer-based neural network that is substantially faster to train. The \texttt{DeepJe…

Azimuthal Correlations within Exclusive Dijets with Large Momentum Transfer in Photon-Lead Collisions Open
The structure of nucleons is multidimensional and depends on the transverse momenta, spatial geometry, and polarization of the constituent partons. Such a structure can be studied using high-energy photons produced in ultraperipheral heavy…

Performance of the CMS High Granularity Calorimeter prototype to charged pion beams of 20–300 GeV/c Open
The upgrade of the CMS experiment for the high luminosity operation of the LHC comprises the replacement of the current endcap calorimeter by a high granularity sampling calorimeter (HGCAL). The electromagnetic section of the HGCAL is base…

Top Secrets: Long-Lived ALPs in Top Production Open
We investigate the discovery potential for long-lived particles produced in association with a top-antitop quark pair at the (High-Luminosity) LHC. Compared to inclusive searches for a displaced vertex, top-associated signals offer new tri…
