The CMS Collaboration has released the results of a new analysis that looks for the subtle influence of “new physics” in the production of a W boson and photon pair.
Jetting through a droplet of matter from the early universe
High energy heavy-ion collisions provide a unique opportunity to study one of the four forces of nature, the strong force, under extreme conditions.
The top quarks' energetic light
Electromagnetic interactions govern everyday life: You see an object when particles of light deposit energy on the retinas in your eyes. Our sense of touch results from the exchange of the same particles, the photons, between the atoms in our skin and the objects we touch.
How many Higgs bosons are there?
In the Standard Model of particle physics, at least one Higgs boson
Under the Radar: Searching for Stealthy New Particles
The standard model of particle physics encapsulates our current know
Observation of a new excited beautiful strange baryon at the CMS experiment
Quantum Chromodynamics (QCD) is the part of the Standard Model of Particle Physics that describes the strong interaction.
The Forward Shielding upgrade: a real engineering challenge for CMS.
As for any other instrument, the CMS experiment needs a “quiet” environment to take data, with the lowest level of background noise. In the CMS detector, background noise is mainly due to energetic particles generated at high eta (i.e.
