Oxygen collisions at the LHC show new indications of extreme state of matter
One year on from the first-ever collisions of oxygen at the Large Hadron Collider (LHC), the main LHC Collaborations – ALICE, ATLAS, CMS and LHCb – have each reported signs of the state of matter known as quark–gluon plasma (QGP) originating from these collisions. QGP is a state of matter that forms under intense pressure

ALICE sees new sign of primordial plasma in proton collisions
The ALICE Collaboration takes a step further in addressing the question of whether a quark–gluon plasma can be formed in proton–proton and proton–nucleus collisions

Shape-shifting collisions probe secrets of early Universe
The first high-energy collisions between light nuclei at the Large Hadron Collider confirm the unusual “bowling-pin” shape of neon nuclei and offer up a new tool to study the extreme state of matter produced in the aftermath of the Big Bang

ALICE finds first ever evidence of the antimatter partner of hyperhelium-4
The finding also represents the first evidence of the heaviest antimatter hypernucleus yet at the LHC

Hearing the sound of quark–gluon plasma
The CMS collaboration has measured the speed of sound in the quark–gluon plasma more precisely than ever before, offering new insights into this extremely hot state of matter

Charm is better than beauty at going with the flow
New ALICE measurements shed light on the dynamics of charm and beauty particles in quark–gluon plasma

ALICE bags about twelve billion heavy-ion collisions
The whopping number of collisions recorded by ALICE during the recent five-week heavy-ion run of the LHC is 40 times greater than the total recorded by the experiment in its previous periods of heavy-ion data taking, from 2010 to 2018

Bikash Sinha (1945 – 2023)
Bikash Sinha(1945 – 2023) — Bikash Sinha, influential Indian scientist and pioneer in quark–gluon plasma and the early Universe, passed away on 11 August at the age of 78. As one of the ALICE experiment’s early visionaries and architects, his impact on heavy-ion physics is unmistakable. Bikash Sinha was born on 16 June 1945 in

Thick-skinned: Scientists determine the thickness of neutron “skin” in lead-208 nuclei
This is the first measurement of the neutron skin of lead-208 using exchanges predominantly involving gluons and it can provide insight into the structure of nuclei and neutron stars

ALICE reports new charmonia measurements in LHC Run 3
The ALICE collaboration presents its first results based on data collected with the upgraded detector in 2022, the first year of Run 3 of the LHC, at the 2023 Quark Matter conference
