‘Tis the season of heavy ions   Last Friday at 3.40 pm, a new #HeavyIon run began at the Large Hadron Colliderthe fourth of #LHCRun3. Usually at the end of each proton run, CERN physicists collide heavy ions to free quarks and recreate the conditions that existed in the early #Universe…

Here we see, for the first time ever, the transport of unbonded protons across the CERN site, a big step towards portable #antimatter. CERN’s Antimatter Factory is the only place in the world where scientists can store and study antiprotons. But scientists at the BASE experiment…

Probing matter–antimatter asymmetry with #AI Using a cutting-edge AI algorithm, the @CMSExperiment has obtained the first evidence of charge–parity (CP) violation in the decay of the strange beauty meson into a pair of muons and a pair of electrically charged kaons. Find out mo…

#OnThisDay in 1993, CERN put the World Wide Web in the public domain, later made available with an open licence, allowing the web to flourish. Here we see Sir Tim Berners-Lee's proposal for the World Wide Web, revised back in May 1990. The World Wide Web will be one of the topi…

CMS releases #HiggsBoson discovery data to the public The @CMSExperiment has recently released, in electronic format, the combination of the measurements that contributed to establishing the discovery of the Higgs boson in 2012. This release coincides with the publication of th…

On this #WorldQuantumDay, we feature CERN theorist John Bell who, 60 years ago, formulated a theorem known as Bell's inequalities. It allowed #quantum entanglement to be tested, which is at the root of promising technologies including quantum computing and cryptography. Bell’s i…

Between the 1960s and the mid-1980s, dozens of women worked #AtCERN as “scanners”. Their job consisted in identifying the trajectories of the particles in the images taken inside the bubble chambers. “Scanning” took place around the clock. The work was done manually, using a pen…

CERN pays tribute to Peter Higgs Peter Higgs’ scientific legacy will extend far beyond the scope of current discoveries. The Higgs boson is linked to some of the most intriguing and crucial outstanding questions in fundamental physics. This still quite mysterious particle theref…

It is with great sadness that we learned of the passing of Peter Higgs. An iconic figure in modern science, Higgs postulated the existence of the eponymous Higgs boson in 1964. Its discovery at CERN in 2012 was the crowning achievement of the Standard Model of particle physics –…

Here we see an antimatter trap. It traps the antiprotons produced by the Antiproton Decelerator (AD), which are necessary for studies of antimatter. #AtCERN, we have several experiments that study antimatter including AEgIS, ALPHA, ASACUSA, BASE, and GBAR. This antimatter trap c…

Not one, not two, but 12 billion collisions 🎆 During the recent five-week heavy-ion run of the #LHC – the first of #LHCRun3 at the highest-ever energy – the @ALICEexperiment recorded about 12 billion lead–lead collisions. This year’s collisions are 40 times greater than the to…

What happens if you drop an anti-apple? In a paper published today in @Nature, the ALPHA collaboration at CERN’s Antimatter Factory shows that, within the precision of their experiment, atoms of antihydrogen – a positron orbiting an antiproton – fall to Earth in the same way as…
