Read article 'Longitudinal asymmetry tracked in heavy-ion collisions'
In a heavy-ion collision, a longitudinal asymmetry arises due to unequal numbers of participating nucleons from the two colliding nuclei, causing a shift in the centre-of-mass (CM) of the overlapping ...
Read article 'The curious case of the J/ψ flow'
Recently, the ALICE collaboration measured the elliptic flow of J/ψ mesons with unprecedented precision in lead–lead (Pb–Pb) collisions and, for the first time, also in proton–lead (p–Pb) col...
Read article 'Fastest spinning fluid clocked by RHIC'
Experiments at the Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Laboratory have found that droplets of quark–gluon plasma (QGP) can spin faster than any other fluid. The immensely h...
Read article 'CMS observes top quarks in proton–nucleus collisions'
The top quark, the heaviest elementary particle in the Standard Model, has been the subject of numerous detailed studies in proton–antiproton and proton–proton collisions at the Tevatron and LHC s...

Deep Inelastic Scattering 2017 (DIS17) demonstrates how deep inelastic scattering (DIS) and related topics permeate most aspects of high-energy physics
Read article 'Precision study reveals proton to be lighter'
A team in Germany has made the most precise measurement to date of the mass of a single proton, achieving a precision of 32 parts-per-trillion (ppt). The result not only improves on the precision of ...
