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.

WWW.Triboson.CMS
Apart from the “World Wide Web,” three Ws may also have a different interpretation in the LHC era.

Does the behaviour of the Higgs boson match the expectations?
The standard model of particle physics is our current best theory to describe the most basic building blocks of the universe, the elementary particles, and the interactions among them.

LHC as the vector boson collider
After the Higgs boson discovery in the year 2012, the standard model of particle physics offers a complete and consistent description of elementary particle interactions that, despite the many attempts, has not been falsified by experimental evidence to date. Nevertheless, several hints indicate that a new more comprehensive theory that includes and extends it may…
