A new LHC: 10 things to look out for
Through an extraordinary routine, the most powerful machine built by humankind is slowly but surely gearing up for its relaunch in March 2015. The Large Hadron Collider (LHC), straddling the national borders of France and Switzerland, will reawaken after two years … Continue reading

Fabiola Gianotti, the first woman Director-General of CERN
The CERN Council has elected a new Director-General to succeed the incumbent Rolf-Dieter Heuer. Fabiola Gianotti, who served as the ATLAS collaboration’s spokesperson from 2009 to 2013 – a period that included the discovery of the long-sought Higgs boson by … Continue reading

Why you should care about the mass of the top quark
In a paper published in Physical Review Letters on July 17, 2014, a team of American researchers reported the most precisely measured value yet of the mass of the top quark, the heaviest fundamental particle. Its mass is so high that … Continue reading

New Higgs results show signs of SUSY
Two years ago, physicists working on the Large Hadron Collider first announced the discovery of a Higgs boson-like particle, setting the high-energy physics community atwitter. And it was only a couple weeks ago that physicists also announced that the particle was … 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

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

The hunt for supersymmetry: Reviewing the first run – 2
I’d linked to a preprint paper [PDF] on arXiv a couple days ago that had summarized the search for Supersymmetry (Susy) from the first run of the Large Hadron Collider (LHC). I’d written to one of the paper’s authors, Pascal Pralavorio … 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
