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 … Read more
From ‘CERN slashes experiment time next year by 20% as energy costs bite’, Physics World, October 12, 2022: To avoid blackouts over the winter, France has launched a national plan to cut energy consumption by 10%. … Mike Lamont, CERN’s director for accelerators and technology, told Physics World that as a large industrial consumer of … Read more
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 … Read more
Because powerful accelerators take at least a decade to realise, physicists have started work on two machines to aid physics research of the future.
This article, as written by me, appeared in print in The Hindu on July 5, 2012. — The ATLAS (A Toroidal LHC Apparatus) collaboration at CERN has announced the sighting of a Higgs boson-like particle in the energy window of 125.3 ± 0.6 GeV. The observation has been made with a statistical significance of 5 sigma. … Read more
As the much-anticipated lead-up to the CERN announcement on Wednesday unfolds, the scientific community is rife with many speculations and few rumours. In spite of this deluge, it may be that we could expect a confirmation of the God particle’s existence in the seminar called by physicists working on the Large Hadron Collider (LHC). The … Read more
