New for Moriond: Catching disappearing particles
Over the past century, physicists have developed a theory governing the fundamental interactions of elementary particles, known as the Standard Model of Particle Physics.

New for Moriond: Higgs does not yet show rare decays into quarkonium pairs
The Standard Model of particle physics asserts that the Higgs boson generates the mass of all fundamental particles.

New for Moriond: First measurement of the effect of virtual Higgs bosons on top quarks
After the discovery of the Higgs boson, CMS observed its interaction with some standard model particles like the bottom and top quark, the tau lepton, and the W and Z boson.

LHC beam pipe to be mined for monopoles
In February, the CMS and MoEDAL collaborations at CERN signed an agreement to hand over to MoEDAL a section of the LHC beam pipe that was located inside CMS between 2008 and 2013. The delicate object, 6 metres long and made of beryllium, will now be sliced and fed into a highly precise magnetic sensors…

First measurement with the LHC Run 2 pp data collected in 2016, 2017 and 2018.
Observation of two excited Bc mesons and first Bc(2S) mass measurement using the LHC data collected in 2016, 2017 and 2018. In November 2018 the proton-proton running of the LHC Run 2 ended. The data collected in 2018 is the largest ever collected at the LHC. Just under three months after the final proton proton…

The CMS collaboration has observed a new production mechanism of top quarks
The top quark is the heaviest particle in the standard model, and since its discovery in 1995 at the Tevatron collider at Fermilab, its study has become prominent in furthering our understanding of fundamental physics.

CMS celebrates the end of LHC Run 2
On Sunday 2nd December CMS recorded the last collisions to bring to a close a very successful LHC second running period (Run 2) that began in 2015. LHC has delivered to CMS 68 fb -1 of proton-proton collisions and almost 1.8 nb-1 of Pb-Pb collisions in 2018, and more than 160 fb-1 overall of proton-proton…
