Read article 'Higgs and top: a new window on dark matter'
With the discovery of a Higgs boson at the LHC two years ago, the last piece of the Standard Model puzzle fell into place. Yet, several mysteries remain, one of which is the enigma of the origin of da...
Read article 'ATLAS finds evidence for the rare electroweak W±W± production'
The Standard Model of particle physics has been extremely successful in predicting a vast variety of phenomena – so successful, that it is easy to forget that some of its predictions have not yet be...
Read article 'New results from ATLAS at Quark Matter 2014'
At the Quark Matter 2014 conference, held in Darmstadt on 19–25 May, ATLAS presented a variety of new results based on lead–lead (PbPb) and proton–lead (pPb) data collected during Run 1 of the...

Supersymmetry is one of the most popular theories beyond the Standard model.
Read article 'CMS sets new constraints on the width of the Higgs boson'
After the discovery of a Higgs boson at the LHC in 2012, all of the measurements of its properties and tests of its spin-parity have proved to be consistent with the predictions of the Standard Model.
Read article 'ATLAS uses t → qH decays to pin down the Higgs'
Since the observation of a Higgs boson at a mass around 125.5 GeV by ATLAS and CMS in July 2012, both collaborations are making every effort to pin it down and decide if it is indeed the Higgs boson ...

Data from the CDF and D0 experiments at the Tevatron have revealed one of the rarest methods of producing a top quark
Read article 'Beauty-quark decays reveal photon polarization'
The Standard Model predicts that the photons emitted in b → sγ transitions, which can only occur through loop-level processes, are predominantly left-handed.
Read article 'First observation of Z-boson production via weak-boson fusion'
The fusion of two weak bosons is an important process that can be used to probe the electroweak sector of the Standard Model.
