…and time flies for the ALICE detector
During the last week of April, the ALICE experiment’s time-of-flight (TOF) detector was completed and installed in the experimental cavern.

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...
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”...
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–...
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...
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...
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...
The result not only confirms a fundamental feature of QCD but enables a direct experimental observation of the non-zero mass of the charm quark.
Jet modification effects are predicted to be strongest in this kinematic region.
The ALICE Collaboration has measured with improved precision the production of J/ψ mesons in collisions of lead nuclei at the highest LHC energy, confirming the role of the “reg...
