“The important thing”, said Einstein, “is not to stop questioning”, and we, as humans, never have. What is it all made up of? How does it fit together? We’ve been yearning to answer these questions for aeons, with our collective efforts culminating…

It has been almost a decade since the Higgs boson (H) was discovered by the LHC experiments, ATLAS and CMS. However, the enthusiasm to study this particle in detail is never ebbing. The H is being scrutinised vigourously in many more ways than the…

Neutrinos (𝝂) are the most intriguing particles in nature. The evolution in our understanding about the characteristics of the neutrinos is also very interesting. The apparent non-conservation of energy in beta decay led Pauli to predict, in 1933, a…

Ask someone what experiments at the CERN-LHC do, they will tell you: ‘You accelerate two protons to very high energy, smash them together and look in great detail at all particles created from the disintegration of the protons.’ etcetera. Well… yes…

Tau leptons are the heavy siblings of muons and electrons, being respectively 170 and 3500 times more massive. Leptons are not sensitive to strong interaction. The tau leptons are however so massive (about 1.8 times heavier than the proton) that…
