Honey, I shrunk the vacuum chambers!

It takes a lot of work to achieve nothingness. The beam pipes within particle accelerators are some of the emptiest regions in the universe. They are evacuated so as to prevent the accelerating particles from colliding with ...

Beams are back in the LHC

The Large Hadron Collider is back in business! On Friday 30 March, at 12:17 pm, protons circulated in the 27-km ring for the first time in 2018. The world's most powerful particle accelerator thus entered its seventh year ...

CERN experiment sees hints of a rare kaon decay

What if the odds of an event occurring were about one in ten billion? This is the case for the decay of a positively charged particle known as a kaon into another positively charged particle called a pion and a neutrino–antineutrino ...

Particle detectors meet canvas

Artworks are part of our cultural and historical heritage. Yet, according to the Fine Arts Expert Institute, nearly half of the artworks circulating on the market are fakes. So how can you tell if a Rembrandt painting is ...

Collimators—the LHC's bodyguards

The performance of the LHC relies on accelerating and colliding beams made of tiny particles with unprecedented intensities. If even a small fraction of the circulating particles deviates from the precisely set trajectory, ...

Particle physics on the brain

Understanding the fundamental constituents of the universe is tough. Making sense of the brain is another challenge entirely. Each cubic millimetre of human brain contains around 4 km of neuronal "wires" carrying millivolt-level ...

Long-lived physics

New particles produced in the LHC's high-energy proton-proton collisions don't hang around for long. A Higgs boson exists for less than a thousandth of a billionth of a billionth of a second before decaying into lighter particles, ...
