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

New results on Higgs bosons’ decay into fermions
For a boson to be the Higgs boson, it has to be intimately related to the physical process it was hypothesized in 1964 to help understand. With new results published on June 22, physicists from CERN, the lab that runs the experiments that first … Continue reading

Gerald Guralnik (1936-2014)
Of the six scientists who came up with the idea of a Higgs boson in the mid-1960s, independently or in collaboration with others, I’ve met all of one. Tom Kibble was at the Institute of Mathematical Science, Chennai, in January 2013 … Continue reading

The hunt for supersymmetry: Reviewing the first run
What do dark matter, Higgs bosons, the electron dipole moment, topological superconductors and quantum loops have in common? These are exotic entities that scientists have been using to solve some longstanding problems in fundamental physics. Specifically, by studying these entities, they expect … Continue reading

The hunt for supersymmetry: Is a choke on the cards?
As scientists have progressed by leaps and bounds in making discoveries and confirming new ideas, they have been disappointed by how one of their favorite theories has been unable to post a positive status update in… years. Continue reading

On the shoulders of the Higgs
On July 4, 2012, when CERN announced that a particle that looked a lot like the Higgs boson had been spotted, the excitement was palpable. A multibillion-dollar search for an immensely tiny particle had paid off, and results were starting … Continue reading

Big science, bigger nationalism.
Nature India ran a feature on March 21 about three Indian astrophysicists who had contributed to the European Space Agency’s Planck mission that studied the universe’s CMBR, etc. I was wary even before I started to read it. Why? Because of that first … Continue reading

Where does the Higgs boson come from?
When the Chelyabinsk meteor – dubbed Chebarkul – entered Earth’s atmosphere at around 17 km/s, it started to heat up due to friction. After a point, cracks already present on the chunk of rock weighing 9,000-tonnes became licensed to widen and eventually … Continue reading

Higgs boson closer than ever
The article, as written by me, appeared in The Hindu on March 7, 2013. — Ever since CERN announced that it had spotted a Higgs boson-like particle on July 4, 2012, their flagship Large Hadron Collider (LHC), apart from similar … Continue reading

LHC to re-awaken in 2015 with doubled energy, luminosity
This article, as written by me, appeared in The Hindu on January 10, 2012. — After a successful three-year run that saw the discovery of a Higgs-boson-like particle in early 2012, the Large Hadron Collider (LHC) at CERN, near Geneva, … Continue reading
