LHCb tightens precision on key measurements of matter–antimatter asymmetry
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 a behavioural difference between matter and antimatter – known as CP symmetry violation – in decays of particles containing quarks, one of the building blocks of matter. But these differences, or asymmetries, are hard to measure and insufficient to explain the matter–antimatter imbalance in the present-day Universe, prompting physicists to both measure precisely the known differences and to look for new ones.

The challenges of the ITk pixel detector
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 of data accumulated by the experiments, in particular the ATLAS experiment.

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