Spin/parity of Higgs-like particle at D0

We present prospects for tests of different spin and parity hypotheses for a particle H of mass 125 GeV produced in association with a vector boson and decaying into a pair of b-quarks. We use the combined analysis of the , and channels based on the full Run II dataset collected at √ s = 1.96 TeV with the D0 detector at the Fermilab Tevatron collider.- France.
