New LHC data puts ‘new physics’ lead to bed
One particle in the big zoo of subatomic particles is the B meson. It has a very short lifetime once it’s created. In rare instances it decays to three lighter particles: a kaon, a lepton and an anti-lepton. There are … Continue reading

US experiments find hint of a break in the laws of physics
At 9 pm India time on April 7, physicists at an American research facility delivered a shot in the arm to efforts to find flaws in a powerful theory that explains how the building blocks of the universe work. Physicists … Continue reading

All goes well on LHC 2.0’s first day back in action
It finally happened! The particle-smasher known as the Large Hadron Collider is back online after more than two years, during which its various components were upgraded to make it even meaner. A team of scientists and engineers gathered at the … Continue reading

Restarting the LHC: A timeline
CERN has announced the restart schedule of its flagship science “project”, the Large Hadron Collider, that will see the giant machine return online in early 2015. I’d written about the upgrades that could be expected shortly before it shut down in … Continue reading

Another window on ‘new physics’ closes
The Standard Model of particle physics is a theory that has been pieced together over the last 40 years after careful experiments. It accurately predicts the behaviour of various subatomic particles across a range of situations. Even so, it’s not … Continue reading
