Tales of colliders contained in 60 illustrious years of CERN Courier offer a rich perspective on the strategic decisions facing the field today.

Harald Fritzsch, who collaborated with Gell-Mann in the early 1970s, describes the steps that led to a full understanding of strong interactions.

The Large Electron Positron collider (LEP) changed particle physics, and CERN, forever. Former Director-General Herwig Schopper describes what it took to make LEP happen.

Two years since it was established, the CERN Alumni Network is proving a valuable careers resource, especially for young physicists who move out of academia, write Laure Esteveny and Rachel Bray.

Among many misconceptions in the description of the proton presented in undergraduate physics lectures is the origin of the proton’s spin. When we tell students about the three quarks in a proton, we usually say […]

When Rutherford discovered the proton in 1919, the only other basic constituent of matter that was known of was the electron. There was no way that the proton could decay without violating charge conservation. Ten […]

How big is a proton? Experiments during the past decade have called well-established measurements of the proton’s radius into question – even prompting somewhat outlandish suggestions that new physics might be at play. Soon-to-be-published results […]

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.

Recent experimental results hint that some electroweak processes are not lepton-flavour independent, contrary to Standard Model expectations. If the effect strengthens as more data are gathered, possible explanations range from new gauge forces to leptoquarks.

The well-established governance, licensing and collaborative mechanisms of open-source software set a standard for open-science movements.

We have conquered the easiest challenges in fundamental physics, says Nima Arkani-Hamed. The case for building the next major collider is now more compelling than ever.

One of the biggest challenges for the CMS collaboration during LS2 is to prepare its detector for the massive future installations necessary for the HL-LHC.

New wheel-shaped detectors that allow a better trigger and measurement capability for muons are among numerous transformations taking place to maintain the ATLAS physics programme into Run 3 and beyond.

Going from the LHC to a 100  km-circumference supercollider is a daunting challenge, but the community has made similar jumps in the past – and the future of fundamental exploration is at stake.

The European Committee for Future Accelerators is assessing individual recognition in large collaborations, not just for the benefit of early-career researchers but for the field as a whole.
