How CMS weeds out particles that pile up
When the CMS experiment records particle collision events, a large number of unwanted extra collisions overlap in the detector and hide the rare particle collision that is worthwhile studying. CMS physicists have developed a new method that gives improved precision for the study of collisions even when occurring together with 50 or more extra interactions.

CMS Measures an Ultra-Rare Decay of a Beautiful and Strange Meson
The Bs meson is a bound state of a strange quark and a beauty antiquark – as such it possesses both beauty and strangeness!

How charming is the Higgs boson?
The CMS collaboration has carried out for the first time a direct search for a Higgs boson decaying into charm quarks, a vital step in understanding the Higgs particle and the Standard Model.

Enhancing the Missing Momentum Microscope
The CMS Collaboration has recently presented an updated search for new invisible particles. The technique capitalizes on the imbalance among the visible particles in a collision that such an object would induce. If dark matter is made of fundamental particles, these could reveal themselves in just this way.

It`s never too late for photons at CMS!
New physics may show up at the LHC in the form of yet unobserved particles which travel inside the detector before decaying, far from the point in space where they were produced. If these particles decay to photons, at CMS we can use the short but measurable time these photons move through the detector to…
