Contribution

It provides a comprehensive analysis framework for testing spin and parity hypotheses of the Higgs-like particle using combined channel data from the Tevatron.

Findings

Prospects for distinguishing spin/parity states of the Higgs-like particle.

Combined analysis enhances sensitivity to particle properties.

Utilizes full Run II dataset for robust testing.

Abstract

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 WH->lvbb, ZH->llbb, and ZH-> vvbb channels based on the full Run II dataset collected at $\sqrt s=1.96$ TeV with the \dzero\ detector at the Fermilab Tevatron collider.
