“…39 and 40 where the behaviors for a CP-even and CP-odd states and for different spins are shown respectively. Another very useful diagnostic of the CP nature of the Higgs boson is the azimuthal distribution between the decay planes of the two lepton pairs arising from the Z, Z ( * ) bosons coming from the Higgs decay [ 26,127,128,129,130,131]. Alternatively, one can study the distribution in the azimuthal angle between the two jets produced in association with the Higgs produced in vector boson fusion [ 132,133,134] or in gluon fusion in Higgs plus jet events [ 135,136].…”
