Read article 'Quark Matter 2014: news from ALICE'
The new results shown by the ALICE collaboration at the Quark Matter 2014 conference in Darmstadt focus principally on the most recent collisions at the LHC – those of protons and lead nuclei (p...
Read article 'Quark Matter 2014: news from CMS'
Although the CMS experiment was designed primarily for precise measurements in proton–proton (pp) collisions, in recent years it has demonstrated exceptional capabilities in studying interactions of...
Read article 'On the trail of exotic particles'
Since the quark model was first conceived 50 years ago, physicists have been searching for "exotic" hadrons – strongly interacting particles that are neither quark–antiquark pairs (mesons) nor th...

Supersymmetry is one of the most popular theories beyond the Standard model.
Read article 'New instrument sees intergalactic filaments'
A team of US astronomers has taken unprecedented images of the intergalactic medium (IGM) – the diffuse gas that connects galaxies throughout the universe. These first pictures of the IGM were o...
Read article 'LHC and Tevatron teams announce first joint result'
The collaborations working on the world’s leading particle-collider experiments have joined forces, combined their data and produced the first joint result from Fermilab’s Tevatron collider and CE...

On 28 March, CERN and the European Space Agency (ESA) signed a framework agreement for future co-operation on research and technology in areas of mutual interest
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 'LHCb’s results become more precise'
At the 2014 Rencontres de Moriond conference in March, the collaboration presented more precise results from a number of different analyses.
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 ...
