### Isolated prompt photon + jet xsection (ATLAS_2012_I1093738)

Spires | arXiv:1203.3161 [hep-ex]

A measurement of the production cross section for isolated photons in association with jets in $pp$ collisions at $sqrt{s} = 7$ TeV. Photons with $|\eta|<1.37$ and $E_T>25$~GeV and jets with $|y|<4.4$ and $p_T>20$ GeV are selected. The differential cross section as a function of the photon transverse energy is measured, for three leading jet rapidity configurations, separately for the cases where the photon and jet rapidities have the same or the opposite sign. The measurement uses 37 pb$^{-1}$ of integrated luminosity collected with the ATLAS detector.

### Inclusive isolated diphoton analysis (ATLAS_2011_S9120807)

Spires | arXiv:1107.0581 [hep-ex]

A measurement of the cross section for inclusive isolated photon production at $sqrt{s} = 7$ TeV. The measurement is done in bins of $M_{\gamma\gamma}$, $p_{T\gamma\gamma}$, and $\Delta\phi_{\gamma\gamma}$, for isolated photons with $|\eta|<2.37$ and $E_T^\gamma>16$~GeV. The measurement uses 37 pb$^{-1}$ of integrated luminosity collected with the ATLAS detector.

### Inclusive isolated prompt photon analysis (ATLAS_2010_S8914702)

Spires | arXiv:1012.4389 [hep-ex]

A measurement of the cross section for inclusive isolated photon production at $sqrt{s} = 7$ TeV. The measurement covers three ranges in $|\eta|$: [0.00,0.60), [0.60,1.37), and [1.52,1.81), for $E_T^\gamma>15$~GeV. The measurement uses 880nb$^{-1}$ of integrated luminosity collected with the ATLAS detector.

### Study the usual underlying event observables in photon + jet events (MC_PHOTONJETUE)

Modification of the MC leading jets underlying event analysis to study the UE in hard photon+jet events. This may be of interest, because the leading QCD dipole structure is different from that in either dijet or Drell-Yan hard processes. Observables are also extended to include the variation of transverse activity as a function of jet-photon balance, and using the photon rather than the jet to define the event alignment.

### Monte Carlo validation observables for photon + jets production (MC_PHOTONJETS)

Different observables related to the photon and extra jets.

### Monte Carlo validation observables for diphoton production at LHC (MC_DIPHOTON)

Different observables related to the two photons
