Abstract: (Oxford University Press)

The search for high-mass diphoton resonance is ongoing at the LHC, and will provide definite evidence of physics beyond the Standard Model once it is discovered. Along with the diphoton resonance, many theoretical models also predict resonances decaying not into a pair of photons but into a pair of highly collimated photon-jets. In this paper, we study how well we can distinguish such diphoton resonance imposters, i.e. diphoton-jet resonances, from diphoton resonances by examining detector responses to the photon-jets. We find that the sum of pT of the first e+e− pair from the photon conversion provides strong discrimination power. We also discuss determination of the lifetime of the light intermediate particle by measuring the photon conversion points.
