     12A search for dark matter is performed using events with large missing transverse momentum and a Higgs boson decaying either to a pair of bottom quarks or to a pair of photons.  We are only interested in the photon pair final state. This analysis searches for excesses over the background-only prediction in events with large pTmiss and a diphoton system that has a reconstructed invariant mass close to the mass of the SM-like Higgs boson h.

    2527=== 3.1 Trigger selection ===
    2628
     29Diphoton triggers with asymmetric transverse energy thresholds (30/18 GeV) are used to select events with the diphoton invariant mass above 95 GeV. The trigger selection uses a very loose photon identification based on the cluster shower shape and loose isolation requirements and a requirement that the ratio of hadronic-to-electromagnetic energy (H/E) of the photon candidates is less than 0.1.

    31 Explained here how the objects are defined.
     35* Photons: Two categories (the barrel–endcap transition region of 1.44 < |eta| < 1.57, where photon reconstruction is not optimal is excluded)
     36      * Photons with |eta|  < 1.44
     37      * Photons with 1.566  < |eta| < 2.5
