Towards monitoring in Run 4 and beyond: LHC experiments exchange perspectives on data quality at the HL-LHC

In March of 2026, experts from ALICE, ATLAS, CMS and LHCb gathered at CERN for a dedicated workshop on Data Quality Monitoring (DQM), bringing together developers, coordinators and detector specialists to discuss how the LHC experiments monitor the…

LHCb completes a long-awaited family of doubly charmed baryons

More than sixty years ago, particle physics was facing a problem of abundance. New subatomic particles were appearing in experiments, but there was not yet a clear organising principle to explain their relationships. In the early 1960s, Murray Gell-…

LHCb explores new light-ion territory with special LHC runs

In summer 2025, the LHC entered new territory. For the first time, the machine delivered p–O, O–O and Ne–Ne collisions to its experiments, as part of a short but technically demanding special ion run. For LHCb, the run provided a rare opportunity to…

Doubly charmed baryon doublet completed with upgraded LHCb

The image on the left presents an artist’s impression of this exotic particle, while the diagram on the right shows a kind of “family tree” of the proton, illustrating how heavier relatives emerge when its quarks are replaced by strange (s), charm…

From top quarks to Higgs bosons: LHCb’s expanding jet programme

Over the past decade, LHCb has steadily evolved from a detector primarily associated with heavy-flavour physics into a broader forward spectrometer able to address an increasingly diverse set of questions in Standard Model and beyond-the-Standard-…

Highlights from the 2nd NGT Technical Workshop

Participants of the 2nd Next Generation Triggers Technical Workshop at the Globe of Science and Innovation. Picture: Mariana Velho From 19 to 21 November 2025, the Next Generation Triggers (NGT) project held its 2nd Technical Workshop at CERN’s…

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…

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: the matter–…

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…

SMOG(2) at LHCb: a space experiment and a bowling alley

A famous aphorism, sometimes attributed to Max Planck, goes “When you change the way you look at things, the things you look at change". Since 2011, the LHCb experiment at the LHC has employed a System for Measuring Overlap with Gas (SMOG) to inject…
