LHCb tightens precision on key measurements of matter–antimatter asymmetry

Published onJune 19, 2023

The LHCb collaboration’s new measurements of matter–antimatter asymmetry in decays of beauty particles are the most precise yet of their kind. The Big Bang is thought to have created equal amounts of matter and antimatter, yet the Universe today is made almost entirely of matter, so something must have happened to create this imbalance. The weak force of the Standard Model of particle physics is known to induce...

The challenges of the ITk pixel detector

Published onMarch 6, 2023

CERN’s Large Hadron Collider (HL-LHC) project aims to push the LHC’s performance to its maximum, to increase the potential for the discovery of new physics and to measure the properties of the Higgs boson with unprecedented precision, in order to search for even small deviations between theory and experimental measurements. The aim of the HL-LHC is to increase the instantaneous luminosity of the LHC to multiply the amount...

Tetiana Berger-Hryn’ova: winner of an ERC Consolidator grant

Published onFebruary 27, 2023

Tetiana Berger-Hryn’ova, leader the ATLAS experiment group at LAPP, has just been awarded a Consolidator grant from the European Research Council (ERC) for the DITTO project. The DITTO project searches for deviations between the standard model of particle physics and experimental observations in events with two leptons. The objective? Pinpoint signs of a New Phenomena at the very high energies.
