CP parameters of the B systems from Tevatron

Recent results on CP parameters of the B systems obtained by the CDF and DØ collaborations using the data samples collected at the Tevatron Collider in the period 2002 – 2007 were presented at the QCD 2008 conference (Montpellier, France). These results include measurements of the mixing phase , decay width difference ΔΓs, and CP violation parameters in the Bs and Bu decays.
