First ions for ALICE and rings for LHCb
Injection tests on 25–29 September delivered heavy ions for the first time to the threshold of the LHC. Particles were extracted from the Super Proton Synchrotron (SPS) and tran...

First jet measurements with ALICE
When quarks and gluons (partons) in opposing beams at high-energy hadron colliders meet they can scatter violently to produce correlated showers of particles, or “jets”...

ALICE prepares for high-luminosity LHC
The LHC is preparing for a major high-luminosity upgrade (HL-LHC) with the objective to increase the instantaneous luminosity to around 2 × 1035 cm–2 s–1 for proton–...

ALICE measures shape of the QGP fireball at freeze-out
Heavy-ion collisions at LHC energies create a hot and dense medium of deconfined quarks and gluons, known as the quark–gluon plasma (QGP). The QGP fireball first expands, cools a...

ALICE shines light inside lead nuclei
The collaboration is using the quasi-real photons which accompany ultra-relativistic proton and lead beams to measure the photoproduction of charmonia and constrain "nuclear shadow...

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 co...
