The Large Hadron Collider is back online, ready to shift from the “what” of reality to “why”

The world’s single largest science experiment will restart on March 23 after a two-year break. Scientists and administrators at the European Organization for Nuclear Research – known by its French acronym CERN – have announced the status of the agency’s upgrades on its Large Hadron Collider (LHC) and its readiness for a new phase of experiments running from now until 2018.Continue reading “The Large Hadron Collider is back online, ready to shift from the “what” of reality to “why””

Which way does antimatter swing?

In our universe, matter is king: it makes up everything. Its constituents are incredibly tiny particles – smaller than even the protons and neutrons they constitute – and they work together with nature’s forces to make up… everything. There was also another form of particle once, called antimatter. It is extinct today, but when theContinue reading “Which way does antimatter swing?”

Where's all the antimatter? New CERN results show the way.

If you look outside your window at the clouds, the stars, the planets, all that you will see is made of matter. However, when the universe was born, there were equal amounts of matter and antimatter. So where has all the antimatter gone? The answer, if one is found, will be at the Large Hadron Collider (LHC),Continue reading “Where's all the antimatter? New CERN results show the way.”

A different kind of experiment at CERN

This article, as written by me, appeared in The Hindu on January 24, 2012. — At the Large Hadron Collider (LHC) at CERN, near Geneva, Switzerland, experiments are conducted by many scientists who don’t quite know what they will see, but know how to conduct the experiments that will yield answers to their questions. TheyContinue reading “A different kind of experiment at CERN”

On meson decay-modes in studying CP violation

In particle physics, CPT symmetry is an attribute of the universe that is held as fundamentally true by quantum field theory (QFT). It states that the laws of physics should not be changed and the opposite of all allowed motions be allowed (T symmetry) if a particle is replaced with its antiparticle (C symmetry) andContinue reading “On meson decay-modes in studying CP violation”
