Distinguishing a spin-0 technipion and an elementary Higgs boson: $V_1$$V_2$ modes with decays into l${¯}_A$$l_B$ and/or q${¯}_A$$q_B$

A neutral spin-0 technipion and an elementary Higgs particle can always be distinguished by an accurate measurement of the coefficient of cos2φ in the azimuthal distribution for a decay mode such as φJ, JJ, JΥ, ΥΥ, φ$Z^0$, ${\mathrm{JZ}}^0$, $Z^0$ $Z^0$, $W^{+}$ $W^{\mathrm{-}}$ where the vector bosons other than φ decay into l${¯}_A$ $l_B$ and/or q${¯}_A$ $q_B$. When this coefficient is least different, other angular coefficients for the case of a Higgs particle must be maximally different from those for a technipion.
