Performance of MicroMegas Electronics in a High-Radiation Environment

Foteini Kolitsi, Theo Alexopoulos, V. D’Amico, F. Fallavollita et autres

To accommodate the anticipated increase in luminosity, the ATLAS experiment at CERN is currently undergoing upgrades. The instantaneous luminosity, in the coming years, is anticipated to attain 7.5×1034cm−2s−1. The most complex upgrade project involves the replacement of the Muon Spectrometer’s inner end-cap …

Upgrade of the RPC detectors data collection and transmission electronics for the ATLAS experiment at High Luminosity LHC

M. Corradi, K. Zachariadou, R. Vari, I. Longarini et autres

Resistive Plate Chambers detector technology is used to trigger muon particles in the ATLAS Muon Spectrometer central region. The foreseen High Luminosity Large Hadron Collider operation imposes replacing their trigger and readout electronics with a Data Collector and Transmitter (DCT) system, which …

A Machine Learning approach to the EFT re-interpretation of the WZjj fully leptonic electroweak production

K. Bachas, I. Karkanias, E. Kasimi, Christos Leonidis et autres

Abstract In this paper we study the use of Machine Learning techniques to set constraints on indirect signatures of physics beyond the Standard Model in Vector Boson Scattering (VBS), in the electroweak (EWK) production of self-interacting W ± Z bosons in association …
