Query: Measurement of the Drell--Yan triple-differential cross section in $pp$
  collisions at $\sqrt{s} = 8$ TeV   This paper presents a measurement of the triple-differential cross section
for the Drell--Yan process $Z/\gamma^*\rightarrow \ell^+\ell^-$ where $\ell$ is
an electron or a muon. The measurement is performed for invariant masses of the
lepton pairs, $m_{\ell\ell}$, between $46$ and $200$ GeV using a sample of
$20.2$ fb$^{-1}$ of $pp$ collisions data at a centre-of-mass energy of
$\sqrt{s}=8$ TeV collected by the ATLAS detector at the LHC in 2012. The data
are presented in bins of invariant mass, absolute dilepton rapidity,
$|y_{\ell\ell}|$, and the angular variable $\cos\theta^{*}$ between the
outgoing lepton and the incoming quark in the Collins--Soper frame. The
measurements are performed in the range $|y_{\ell\ell}|<2.4$ in the muon
channel, and extended to $|y_{\ell\ell}|<3.6$ in the electron channel. The
cross sections are used to determine the $Z$ boson forward-backward asymmetry
as a function of $|y_{\ell\ell}|$ and $m_{\ell\ell}$. The measurements achieve
high-precision, below the percent level in the pole region, excluding the
uncertainty in the integrated luminosity, and are in agreement with
predictions. These precision data are sensitive to the parton distribution
functions and the effective weak mixing angle.
