Query: Measurement of Higgs boson production in the diphoton decay channel in
  $pp$ collisions at center-of-mass energies of 7 and 8 TeV with the ATLAS
  detector   A measurement of the production processes of the recently discovered Higgs
boson is performed in the two-photon final state using 5.4 fb$^{-1}$ of
proton-proton collisions data at $\sqrt{s}=7$ TeV and 20.3 fb$^{-1}$ at
$\sqrt{s}=8$ TeV collected by the ATLAS detector at the Large Hadron Collider.
The number of observed Higgs boson decays to diphotons divided by the
corresponding Standard Model prediction, called the signal strength, is found
to be $\mu = 1.17 \pm 0.27$ at the value of the Higgs boson mass measured by
ATLAS, $m_{H}$ = 125.4 GeV. The analysis is optimized to measure the signal
strengths for individual Higgs boson production processes at this value of
$m_{H}$. They are found to be $\mu_{\mathrm{ggF}} = 1.32 \pm 0.38$,
$\mu_{\mathrm{VBF}} = 0.8 \pm 0.7$, $\mu_{{WH}} = 1.0 \pm 1.6 $, $\mu_{{ZH}} =
0.1 ^{+3.7}_{-0.1} $, $\mu_{{t\bar{t}H}} = 1.6 ^{+2.7}_{-1.8} $, for Higgs
boson production through gluon fusion, vector-boson fusion, and in association
with a $W$ or $Z$ boson or a top-quark pair, respectively. Compared with the
previously published ATLAS analysis, the results reported here also benefit
from a new energy calibration procedure for photons and the subsequent
reduction of the systematic uncertainty on the diphoton mass resolution. No
significant deviations from the predictions of the Standard Model are found.
