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 many types of leptons and anti-leptons. Two are electrons/anti-electrons and muons/anti-muons. According to the existing… 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 are looking for flaws in it because the theory doesn’t have answers to some questions… 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 collider’s control room at CERN over the weekend – giving up Easter celebrations at home… 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 2012. They range from new pixel sensors and safety systems to facilities that will double the… 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 complete: it can explain neither gravity nor anything about the so-called dark universe. Physicists searching… Continue reading

Dr. Stone on the Higgs search
On December 10, 2012, I spoke to a bunch of physicists attending the Frontiers of High-energy Physics symposium at the Institute of Mathematical Sciences, Chennai. They included Rahul Sinha, G. Rajasekaran, Tom Kibble, Sheldon Stone, Marina Artuso, M.V.N. Murthy, Kajari Mazumdar, and Hai-Yang Cheng, amongst others. All their talks, obviously, focused on either the search… Continue reading

Window for an advanced theory of particles closes further
A version of this article, as written by me, appeared in The Hindu on November 22, 2012. — On November 12, at the first day of the Hadron Collider Physics Symposium at Kyoto, Japan, researchers presented a handful of results that constrained the number of hiding places for a new theory of physics long believed… Continue reading
About Me
I’m a science editor and writer in India, interested in high-energy and condensed-matter physics, research misconduct, pseudoscience, science’s relationship with society, epic fantasy, open source/access/knowledge systems, H.R. Giger’s art, Goundamani’s comedy, Factorio, and most things that require a lot of time to get the hang of.
