Abstract
The CDF and D0 experiments at the Tevatron ppbar collider have pioneered and established the role of flavor physics in hadron collisions. A broad program is now at its full maturity. We report on three new results sensitive to physics beyond the standard model, obtained using the whole CDF dataset: a measurement of the difference of CP asymmetries in

and

decays of

mesons, new bounds on the

mixing phase and on the decay width difference of
B

s
mass-eigenstates, and an update of the summer 2011 search for
B

(

mesons decaying into pairs of muons. Finally, the D0 confirmation of the observation of a new hadron, the
χ

(3P)
state, is briefly mentioned.
