The 2015 edition of the European Physical Society Conference on High Energy Physics (EPS-HEP 2015), which took place in Vienna in July (“Vienna hosts a high-energy particle waltz”), provid...
Read article 'ALICE goes forward with the ridge in pPb collisions'
One of the hottest debates at the LHC is the potential emergence of collective effects in proton–lead (pPb) collisions, prompted by the discovery of double ridge structures in angular correlatio...

Read article 'STAR helps to pin down a key phenomenon in gold collisions'
The Brookhaven National Laboratory has published new evidence indicative of a "chiral magnetic wave" rippling through quark–gluon plasma.
Read article 'First full jet measurement in Pb–Pb collisions with ALICE'
In high-energy collisions at the LHC, quarks and gluons occasionally scatter violently and produce correlated showers of particles, or “jets”. In proton–proton collisions, the rate o...
Read article 'COMPASS measures the pion polarizability'
The COMPASS experiment at CERN has made the first precise measurement of the polarizability of the pion – the lightest composite particle built from quarks.
Read article 'CMS heads towards solving a decades-long quarkonium puzzle'
Quarkonia – charm or beauty quark/antiquark bound states – are prototypes of elementary systems governed by the strong force.
Read article 'ALICE sheds light on particle production in heavy-ion collisions'
New results from the ALICE collaboration are providing additional data to test ideas about how particles are produced out of the quark–gluon plasma (QGP) created in heavy-ion collisions at the L...
Read article 'CMS measures the ‘underlying event’ in pp collisions'
Ever since the earliest experiments with hadron beams, and subsequently during the era of the hadron colliders heralded by CERN’s Intersecting Storage Rings, it has been clear that hadron collisions...
