The DRD1 Gaseous Detectors School 2025 will take place at the FTD at Bonn University from September 17-24, 2025. The school focuses on state-of-the-art gaseous detector technologies including MPGDs, ...

With a new measurement imminent, the Courier explores the experimental results and theoretical calculations used to predict ‘muon g-2’ – one of particle physics’ most precisely known quantities and ...

What a proton is depends on how you look at it, or rather on how hard you hit it. A century after Rutherford’s discovery, our picture of this ubiquitous particle is coming into focus, says Amanda ...

André de Gouvêa explains why neutrino masses imply the existence of new fundamental fields. Misfits Massive neutrinos are not part of the Standard Model. Credit: Symmetry After all these years, ...

Patrick Koppenburg and Marco Pappagallo survey the 23 exotic hadrons discovered at the LHC so far. Twenty-three exotic states Five pentaquarks and 18 tetraquarks have been discovered so far at the LHC ...

Frontier instruments like the LHC and its detectors not only push back the boundaries of our knowledge, but also catalyse innovative technology for medical applications, writes Manuela Cirilli.

The Courier matched photos from CERN’s first 25 years to current experts and asked them to reflect on how much has changed across 70 years of science. The past seven decades have seen remarkable ...

From targets to absorbers, beam-intercepting devices are vital to CERN’s accelerator complex. Marco Calviani describes the major upgrades taking place to prepare for the high-luminosity LHC, and the ...

Jochen Klein and Marco van Leeuwen describe the physics motivation, detector concept and projected performance of a next-generation heavy-ion programme for LHC Runs 5 and 6. Brand new ALICE 3 is built ...

The recently installed, upgraded ALICE inner tracking system is the largest pixel detector ever built and the first at the LHC to use monolithic active pixel sensors, describe Luciano Musa and ...

Thanks to new theory calculations and keenly awaited measurements of the magnetic moment of the muon, a longstanding anomaly may soon be resolved either in favour of new physics or the Standard Model.

Marek Karliner and Jonathan Rosner ask what makes tetraquarks and pentaquarks tick, revealing them to be at times exotic compact states, at times hadronic molecules and at times both – with much still ...
