Abstract

We probe the spin (J) and parity (P) of the Standard Model Scalar (SMS) using existing searches sensitive to its production rate and kinematic properties. In particular, we search for the SMS decaying to a pair of b-quarks produced in association with a W boson decaying leptonically. By exploiting the differences in kinematic observables, namely the transverse mass of the final state products (M_T), we attempt to distinguish between three possible J^P hypotheses: the standard model prediction (\jpzp), a pseudoscalar (\jpzm), and a graviton-like particle (\jptp). With 9.7 fb^-1 of data collected at the D0 experiment we show the expected sensitivity to different spin and parity hypotheses.
