Leptons Popping out of Thin Air
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 (LHC) could be producing never-before-seen particles that travel into the CMS detector before transforming into known particles. And because no one knows for sure what undiscovered…

Increased confidence for the Higgs boson coupling to the charm quark
CMS experiment recently made a new measurement of Higgs boson coupling strength to the charm quark, putting the best constraint so far on the anomalous value compared to the prediction from the standard model. Using the complete data volume of Run 2, and using state-of-the-art techniques of machine learning aptly, the scientist developed a very…

Sensing the invisible Higgs at the LHC
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.

Does the top quark respect all the leptons equally?
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.

Hunting for anomalous interactions between the Higgs bosons and the top quarks
Since the Higgs boson discovery in 2012 by the CMS and the ATLAS collaborations, the interaction of the Higgs boson with other fundamental particles as well as with itself are studied with ever-increasing precision to pin down the nature of this new particle.

The Z and the b
The collision of high-energy protons at the LHC breaks them apart and allows us to look at its constituents.

Life of the Higgs boson
The Higgs boson is peculiar in many respects.

Twice the Higgs, twice the fun!
The Higgs boson, once the sought-after holy grail of particle physics, has now been with us for almost a decade.
