• Connection between diphoton and 3-boson channels 29. sep. 2016 13:05

Anastasia Sokolenko, FI

In this work we propose a new interesting channel for searching new physics at the LHC. This channel is connected to the diphoton channel via electroweak gauge symmetry of the Standard Model (SM). We discuss the possibility that an apparent diphoton signal is in fact produced by the 4-photon channel, where a pair of collimated photons is misidentified as 1 photon due to finite angular resolution of the detector. In this case we expect that the gauge symmetry of the SM connects the diphoton channel to three boson channels. Also we notice that the same mechanism could give an experimental signature of $Z\rightarrow \gamma\gamma$ decay, which is theoretically forbidden by the Landau-Yang theorem. For definiteness we illustrate these ideas using one of the models that was discussed to explain the recent 750 GeV resonance, even if the later signal was not confirmed.
