Abstract
Most recent results on spin-parity (JP) measurement of the new particle observed in the Higgs boson search in the H -> ZZ* -> 4l decay channel are presented. The JP state of this boson is probed exploiting two complementary multivariate analysis techniques (using matrix element description of the process or a Boosted Decision Tree discriminant). Results, based on about 25 fb(-1) collected in pp collisions at root s - 7 and 8 Tev, show how the 0(+) state is favoured against specific 0, 2 I, 2 and spin 1 hypotheses.
