... After travelling only 2 millimetres in the detector, the beauty quark decayed to a lighter quark – still paired with the original up quark – and the extra energy was carried off in the form of electron-like particles called muons. “It’s a very rare event; it’s like a needle in a haystack,” says Andr ...

He thought that atoms were similar to the circular particles that you have drawn and that the bullets would all interact with all the gold atoms in abou ...

The Physics behind Nuclear Fusion
... The binding energy curve shows that energy can be released if two light nuclei combine to form a single larger nucleus. This process is called nuclear fusion. The process is hindered by the electrical repulsion that acts to prevent the two particles from getting close enough to each other to be with ...

Compact Muon Solenoid
The Compact Muon Solenoid (CMS) experiment is one of two large general-purpose particle physics detectors built on the Large Hadron Collider (LHC) at CERN in Switzerland and France. The goal of CMS experiment is to investigate a wide range of physics, including the search for the Higgs boson, extra dimensions, and particles that could make up dark matter.CMS is 21.6 metres long, 15 metres in diameter, and weighs about 14,000 tonnes. Approximately 3,800 people, representing 199 scientific institutes and 43 countries, form the CMS collaboration who built and now operate the detector. It is located in an underground cavern at Cessy in France, just across the border from Geneva. In July 2012, along with ATLAS, CMS tentatively discovered the Higgs Boson.
