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 (…

One of the intriguing questions in particle physics is the origin of mass of the fundamental particles. The question we ask is: is the Higgs boson responsible for the masses of all the known particles? The well-established theory of particle physics…

A few months are left before the start of Run 3 at CERN. With the timely completion of all upgrades planned for Long Shutdown 2 (LS2), in the last weeks the CMS detector has been set in its closed configuration. If this sounds like an ordinary or…

The challenge of Run3: CMS is preparing to resume its operations for the Run-3 of the Large Hadron Collider (LHC) after a 3-year long shutdown called LS2 (2019-2021). The time of LS2 was used to perform upgrades, which are regularly conducted in the…

  One of the fundamental puzzles we face today is the dark matter (the dunkle materie, as called by the Swiss physicist Fritz Zwicky back in 1933) in the universe. It is highly abundant (almost five times more than all the objects put together in…

The word lepton comes from the Greek λεπτός (leptós,) meaning “small”;  the electrically charged leptons (electrons, muons, and taus) have much smaller masses than their counterparts in the quark sector. For example, the tau particle is the heaviest…

The collision of high-energy protons at the LHC breaks them apart and allows us to look at its constituents. Surely there are more interesting stuff in store, compared to the usual constituents at lower energy, the up and the down type quarks.…
