Read article 'ALICE probes partons inside lead nuclei'
The large centre-of-mass energy and luminosity of the LHC have made possible the first measurements of electroweak-boson production in ultrarelativistic heavy-ion collisions.
Read article 'ALICE closes in on parton energy loss'
In Pb-Pb collisions, the spectra are modified by the energy loss that the partons suffer when propagating in the quark-gluon plasma.
Read article 'Oddball antics in proton–proton collisions'
The TOTEM collaboration at CERN has uncovered possible evidence for a subatomic three-gluon compound called an odderon, first predicted in 1973.
Read article 'ALICE puts limits on jet quenching in p–Pb collisions'
What are the essential requirements for the formation of a quark–gluon plasma? Do only the most violent, head-on lead–lead (Pb–Pb) interactions at the LHC provide such conditions?
Read article 'ALICE investigates charm-quark hadronisation'
These two results suggest that charmed baryon formation might not be universal, and that the baryon/meson ratio depends on the collision system.

The sixth International Conference on New Frontiers in Physics (ICNFP) took place on 17–29 August in Kolymbari, Crete.
Read article 'Copper reveals nickel’s doubly magic nature'
Teams at CERN’s ISOLDE facility and at RIKEN in Japan have found evidence that an exotic isotope of the metallic element nickel (78Ni) is doubly magic, opening a new vista on an important region of ...
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...
