In the Standard Model the Higgs mechanism is used for the electroweak symmetry breaking. This mechanism also provides mass to the W and Z particles and the fermions. Although the Higgs boson is a integral part of the Standard Model it could not be found. One of the main goals of the Tevatron collider at the Fermi National Accelerator Laboratory is to find the Higgs particle. The D0 experiment has started data taking last year.  The Higgs mechanism and the D0 expermiment are reviewed.
