The ATLAS experiment at CERN finds evidence of a rare Higgs boson Dalitz decay to two leptons and a photon

The new collection of 200 additional software packages make most ATLAS software open and reinforces ATLAS’s commitment to open science

The result surpasses previous best mass limits achieved with CERN’s predecessor collider to the LHC

The ATLAS Inner Detector can measure the position of charged particles that pass through it to better than a 100th of a millimetre! To reach that precision, the detector must be aligned to equal or better accuracy

The ATLAS experiment reports the observation of photon collisions producing weak-force carriers and provides further insights into their interactions

The ATLAS and CMS experiments at CERN have announced new results which show that the Higgs boson decays into two muons

A new ATLAS measurement of a key feature of the Standard Model known as lepton flavour universality suggests that a previous discrepancy measured by the LEP collider in W boson decays may be due to a fluctuation

Our third story in the LHC Physics at Ten series takes us on a deeper dive into the Higgs boson

The ATLAS and CMS collaborations presented their latest results on new signatures for detecting the Higgs boson at CERN’s Large Hadron Collider

Our second story in the LHC Physics at Ten series visits the LHC’s most important discovery so far

The Higgs boson plays a crucial role in the search for dark matter at the Large Hadron Collider

The ATLAS and CMS collaborations used the full LHC Run 2 dataset to obtain new insights into the interaction
