D0
 

Goals:

The D0 experiment at the Fermilab proton-antiproton collider Tevatron is a multi-purpose detectors system allowing to address a wide spectrum of physics subjects within the Standard Model such as top quark production and properties measurements, QCD, W and Z gauge bosons studies, b-quark physics.

The D0 experiment also allows to search for the Higgs boson as well as new physics beyond the Standard Model such as supersymmetry and extra-dimensions.

Before the advent of the LHC, the Tevatron is currently the most energetic collider in the world and the only collider where the top quark as well as possibly a Higgs boson, if sufficiently light, can be produced.
