PHYSICS 113: Contemporary Physics – Midterm Exam Solution Key
... The up quark has a charge of +2/3, and since all baryons have 3 quarks, a ∆++ must have (uuu) . Strictly speaking, u, c, or t all have +2/3, so we’ll accept any combination of 3 of them, but if you’re curious, the actual particle is just made of ups. (b) What are the charge, baryon number and lepton ...

... While theoretical physicists are busy formulating possible explanations, the experimenters are not sitting idly about. “A more precise determination of the Rydberg constant would allow us to verify whether our measurement is correct,” explains Pohl. Physicists use this constant to calculate the diff ...

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.
