The installation of a new prototype of  CMS muon chambers was completed last December. With these installations, the CMS detector is taking further steps towards the HL-LHC era at CERN.  With the future High Luminosity Large Hadron Collider (HL-LHC…

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…

Before saying goodbye to 2021, we’re proud to look back at major milestones reached by CMS collaboration both on physics results and detector upgrades along the year. It is impossible to mention all the achievements on various fronts; what we…

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…

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.…

As the experiments at the Large Hadron Collider (LHC) brace for the start of Run 3 of the accelerator’s programme in 2022, the CMS collaboration has released a new batch of research-quality open data recorded by the CMS detector in 2015, the first…

  During the CERN pilot beams at the end of October, for the first time CMS has reconstructed online the LHC collision data with Graphic Processing Units (GPUs). At CMS, the High Level Trigger (HLT) is responsible for analysing in real time up to…

The Higgs boson is peculiar in many respects. Like most other elementary particles, it is unstable and lives only for an extremely short time, 1.6 x 10-22 seconds, according to the established theory of particle physics (the standard model). Pretty…

As the end of Long Shutdown 2 (LS2) is getting closer, CERN along with the experiments at the Large Hadron Collider (LHC) is preparing to welcome the most awaited Run 3 next year. The CMS experiment geared up for the two weeks of CERN pilot beams in…

The Large Hadron Collider (LHC) has been providing particle collisions at larger and larger luminosities over the years, thanks to a series of upgrades. However, the most anticipated upgrade has yet to come: the High Luminosity LHC (HL-LHC). Here…
