Particle Physics Collaboration (PPC)


The Particle Physics Collaboration (PPC) group pursues the completion the of Standard Model of particle physics, a set of theories which describe all known phenomena concerning the electroweak and strong interactions, and explores physics beyond the Standard Model. The group does this by analyzing a large amount of data in high-energy proton-proton collisions collected by the Compact Muon Solenoidal (CMS), one of two multi-purpose particle detectors installed at interaction points of the Large Hadron Collider (LHC) at CERN, Geneva, Switzerland.

This group plays a leading role in the Compact Muon Solenoidal (CMS) collaboration at the LHC, composed of 183 institutions from 38 countries, with 3000 scientists and engineers. After 20 years of design and construction, the CMS detector, the heaviest detector ever constructed for particle physics which weighs 14,000 tons, started collecting proton-proton collision data in October 2009.

Engaging in HEP planning of the future

High Energy Physics or Particle Physics has a long history which you can arguably trace back to the Greeks in 600 BC, where the idea of the atom (atomos – ‘uncuttable’) was first invented in thought experiments.
