Higgs boson production and properties at the Tevatron

We present the searches for the Standard Model Higgs boson, using the full Run II dataset of the Fermilab Tevatron p p collider, collected with the CDF and D detectors. A signicant excess of events is observed, consistent with the presence of a Standard Model Higgs boson of mass 125 GeV. We also present tests of dierent spin/parity hypotheses, performed in the V H ! V b b channels at D, and new searches in invisible modes conducted at CDF.
