The upgrade of the Large Hadron Collider is expected to return nearly twice its cost to societyIn 1931, Paul Dirac predicted a particle with the same mass as the electron and the opposite charge. This particle, the “positron”, was observed the following year, in a cloud-chamber photograph taken by Carl Anderson. Of course, neither envisaged any medical applications of the discovery. But, today, PE

Work has begun to disconnect the focusing magnets on either side of the ATLAS and CMS experiments, a key step on the road to the HiLumi LHCThe 27 km circumference of the Large Hadron Collider (LHC) contains thousands of magnets of different types – dipoles, quadrupoles, sextupoles, octupoles, decapoles, etc. – which each play a very specific role. Among them are the inner triplets: sets of three q

The mind-bending phenomenon is now becoming evident in a new particleQuantum entanglement is certainly one of the stranger concepts to have emerged from the melting pot of 20th-century physics. Many great physicists, including Einstein, struggled to accept that the phenomenon could be real but, for decades now, the number of examples demonstrating it has been increasing. And, recently, the ATLAS a

Looking back on his time at CERN, Neville Burke recalls some of the memorable moments and people that shaped his experience at the Laboratory. Among his favourite memories is his supervisor drawing on a napkin, reminding him that “a lot of science is done on napkins.” He also shares the story of how Peter Higgs signed his thesis.

The NA64 experiment at CERN has searched for dark matter since 2016 by looking for energy that goes missing when particles strike its detectorIn particle physics, energy is never lost. When particles collide or decay, all the initial energy they carry must be conserved in the resulting products, and a shortfall signals that something has escaped unseen. It was the energy missing from radioactive d

Researchers set new constraints on the production rate of double-Higgs bosons, providing insight into how the Higgs boson interacts with itselfFinding one Higgs boson was hard enough, but physicists at the Large Hadron Collider (LHC) are hunting for something even more elusive: pairs of Higgs bosons.
