Elementary Particle Physics

LHCb is a high-energy particle physics experiment at the Large Hadron Collider at CERN. Its main goal is to perform high-precision measurements of CP-symmetry violating processes in the decay of B-mesons. These measurements will permit important tests of the Standard Model of high energy particle physics. CP violation also plays in important role in cosmology, where it is required in order to explain the observed dominance of matter over anti-matter in our universe.

CTA is an initiative to build a next generation ground-based gamma-ray Cherenkov Telescope Array, which will provide the deepest ever insight into the non-thermal high-energy universe. It foresees a factor of 5-10 improvement in sensitivity in the current energy domain of about 100 GeV to some 10 TeV and an extension of the accessible energy range to well below 100 GeV and above 100 TeV.

H1 was a high energy physics experiment at DESY, Hamburg, studying deep inelastic scattering of electrons and protons at HERA. It stopped data taking in 2007 but the analysis of the collected data still produces new results.
