Detecting photons at LHC

  1. Jan 3, 2014 #1
    Hi all,

    Is it not preferable to detect a particle at the LHC with final states of photons, that when I read
    in many papers I find for example for a particle beyond SM like an octet scalars if they could decay
    into jets and photons+jets ( S^+ -> S^- A -> t b A), only jets channels take a concern, so do jets or
    leptons detection has advantages than photons siganls ?

    Where are the photons in your process?
    And if you just look at the different channels, are there different numbers of photons?

    Photons are nice (better energy resolution as for jets), but for most processes they are less frequent than jets.
    Leptons are even better - you can track their path and get a good position and momentum resolution. And muons are easy to identify.
