ATLAS Experiment releases new study of ultra-rare B-meson decay

The study of hadrons—particles that combine quarks to form mesons or baryons—is a vital part of the physics programme by researchers of the ATLAS Experiment at CERN. Their analysis has not only perfected the understanding ...

Higgs boson observed decaying to b quarks

On 9 July, at the 2018 International Conference on High Energy Physics (ICHEP) in Seoul (South Korea), the ATLAS experiment reported a preliminary result establishing the observation of the Higgs boson decaying into pairs ...

Quarks observed to interact via minuscule 'weak lightsabers'

Two among the rarest processes probed so far at the Large Hadron Collider, the scattering between W and Z bosons emitted by quarks in proton-proton collisions, have been established by the ATLAS experiment at CERN.

ATLAS experiment studies fragments of the top quark

Top quarks in the Large Hadron Collider (LHC) proton-proton collisions are predominantly produced in pairs, with one top quark and one top antiquark. In order to measure the production rates of top quark pairs, the ATLAS ...

On top of the top quark—new ATLAS experiment results

Physicists from the ATLAS Experiment at CERN have presented exciting new results at the 10th International Workshop on Top Quark Physics (TOP2017), held in Braga (Portugal). The conference brought together experimental ...

Searching for invisible particles with the ATLAS Experiment

As the Large Hadron Collider (LHC) smashes protons at a centre-of-mass energy of 13 TeV, it creates a rich assortment of particles that are identified through the signature of their interactions with the ATLAS detector. But ...
