  Kinematic distributions in the decays of the newly discovered resonance to
four leptons are a powerful test of the tensor structure of its couplings to
electroweak gauge bosons. We present an analytic calculation for both signal
and background of the fully differential cross section for the `Golden Channel'
$e^+e^-\mu^+\mu^-$ final state. We include all interference effects between
intermediate gauge bosons and allow them to be on- or off-shell. For the signal
we compute the fully differential cross section for general scalar couplings to
$ZZ$, $\gamma\gamma$, and $Z\gamma$. For the background we compute the leading
order fully differential cross section for the dominant contribution coming
from $q\bar{q}$ annihilation into $Z$ and $\gamma$ gauge bosons, including the
contribution from the resonant $Z\rightarrow 2e2\mu$ process. We also present
singly and doubly differential projections and study the interference effects
on the differential spectra. These expressions can be used in a variety of ways
to uncover the nature of the newly discovered resonance or any new scalars
decaying to neutral gauge bosons which might be discovered in the future.
