Results from the Tevatron: CDF and D0

CDF and DO experiments have been taking data at the Tevatron collider at Fermilab since 2002. Many important physics results have been achieved during these years, going from the discovery of the top quark to the precise measurement of the oscillation frequency of the Bg mesons. The very high luminosity reached recently by the Tevatron machine allows the experiments to search for very rare processes, like Higgs boson production, and in general any new physics process. The results described in this paper have as guiding thread the new physics search in several different fields going from quantum cromodynamics to supersymmetric extension of Standard Model, getting through B-meson physics
