Marek Gazdzicki: Four Decades at the SPS – and Still Surprised by Strong Interactions
Marek Gazdzicki: Four Decades at the SPS – and Still Surprised by Strong Interactions After nearly two decades at the helm of NA61/SHINE, Marek Gazdzicki reflects in this interview on a lifetime at the SPS — from proposing the world’s first two-dimensional scan of nuclear collisions to the unexpected discovery of a large isospin symmetry

Light ions at the LHC: first results from oxygen–oxygen and neon–neon collisions
Light ions at the LHC: first results from oxygen–oxygen and neon–neon collisions This summer, the Large Hadron Collider (LHC) delivered its first-ever collisions between light ions, opening a new chapter in the study of nuclear structure and the quark–gluon plasma (QGP) – the extreme state of matter that existed in the first instants of the

The Asymmetry of the Universe: First Observation of CP Violation in Baryons
The Asymmetry of the Universe: First Observation of CP Violation in Baryons “What is that which always is and has no becoming, and what is that which becomes and never is?” — Plato, Timaeus 27d–28a It may sound like pure philosophy, yet for physicists it speaks to one of the most profound mysteries in physics:

ATLAS explores the quark–gluon plasma with light-ion collisions
ATLAS explores the quark–gluon plasma with light-ion collisions In July 2025, ATLAS recorded the first-ever collisions of light ions at the LHC — oxygen–oxygen (O–O) and neon–neon (Ne–Ne) — marking a new phase in the study of strongly interacting matter. These short, intense runs provided a unique opportunity to explore the transition between conventional hadronic

New Staff Members and Fellows
New Staff Members and Fellows Roberto Acciarri Hello! I’m Roberto, and I’ve recently joined the CERN EP-NU group as a staff physicist. I’m an experimental physicist with 10+ years of experience in the development, construction, and installation of liquid Argon TPC detectors for various neutrino and test beam experiments. My main contributions will focus on supporting the

LHCb explores new physics in special light-ion LHC runs
LHCb explores new physics in special light-ion LHC runs The LHC carried out a special run programme early summer. First results were reported by the ALICE, ATLAS, CMS and LHCb experiments at the Initial Stages of High-Energy Nuclear Collisions conference. These results were also presented at a CERN seminar and reported in a CERN news.

CMS explores light-ion collisions: suppression, scaling, and collectivity
CMS explores light-ion collisions: suppression, scaling, and collectivity The CMS experiment has reported first results from the LHC’s dedicated oxygen–oxygen (O–O) and neon–neon (Ne–Ne) collision run, offering an unprecedented look at quark–gluon plasma (QGP) formation in light-ion systems. These studies address long-standing questions about the minimal conditions required for QGP droplets to form and how
