The Large Hadron Collider (LHC) offers a unique opportunity to probe the internal structure of protons, with great precision and at unprecedented energies. According to Feynman’s parton model, protons are made up of three quarks, two “up”…

Since the LHC collider started operating, more than a decade ago, several trillions of proton-proton collisions have taken place. Scientists have been painstakingly investigating the products of these collisions, as registered in their detectors, to…

Since the discovery of the Higgs boson (H) in 2012, the ATLAS and CMS experiments at the CERN-LHC have made significant progress in understanding the properties of this new particle. It has zero spin, in agreement with the prediction of the well-…

The biggest achievement of the LHC so far has been the observation of a Higgs boson in 2012. This is an outstanding confirmation of what today is the established theory that describes the fundamental interactions of particles, known as the standard…

“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…

CMS casts a wide net in the hunt for undiscovered particles
Physicists at the CMS experiment have been searching for new particles in exciting new places. In a recently published paper, they explore the possibility that the Large Hadron Collider (…
