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...
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...
Read article 'LHCf investigates proton–lead collisions'
The final run of the LHC in January 2013 prior to the start of the current long shutdown provided collisions between a beam of protons and a beam of lead ions, allowing the LHCf experiment to make fur...
Read article 'The Mass Gap and its Applications'
This book presents a new method – the introduction of the "mass gap" – first suggested by Arthur Jaffe and Edward Witten at the turn of the millennium.
Read article 'Jets give clues to the geometry of proton–nucleus collisions'
Studies of the centrality-dependence of jet production in proton–lead collisions in ATLAS at the LHC are yielding surprising results.
Read article 'Charmonium produced in unusual topology sheds light on QCD'
The LHCb collaboration has released updated measurements of central exclusive production of the J/ψ and ψ(2S) mesons.
