SUS-15-009: Search for natural GMSB in events with top quark pairs and photons (8 TeV)

Line: 105 to 105
  I agree with the comment and have made the abstract to be very similar to your suggestion.

  • Fig. 1: Since this is not a real Feynman diagram where time arrows play a role and need to be correct, I would remove all arrows and just show lines

Okay.
 
  • Fig. 1 caption: What is GMM? My suggestion for a less redundant caption:
    Feynman diagram of the GMSB scenario of interest. With stop quarks as the lightest squark, their pair-production would be the dominant production mechanism for SUSY in pp collisions at the LHC. Assuming a bino-like neutralino NLSP, each stop would decay to a top quark and a neutralino, with the neutralino decaying to a gravitino and a photon. Shown above is the electron+jets or muon+jets final state of the top pair decay.

For the GMM comment I agree, however in small points in your suggestion I would disagree. I feel it's best to keep the language of "lightest squark or gluino" versus just "lightest squark". The stop being much lighter than the gluino is important to the analysis, otherwise any allowed gluino production would be very close to those in the inclusive photon searches (ie no third-generation decays) we've published previously. "Squark or gluino" is a bit confusing I accept, so if there are any recommendations how to clean this up while retaining the gluino caveat I'd be happy to change it.
I also feel the language "stop squark" is preferred over "stop quark" for clarity. More cumbersome but complete is "scalar quark" or "scalar top partner", but I've tried to consistently use "stop squark" to keep it distinct. An updated caption now reads:
"Feynman diagram of the GMSB scenario of interest. With stop squarks as the lightest squark or gluino, their pair production would be the dominant production mechanism for SUSY in pp collisions at the LHC. Assuming a bino-like neutralino NLSP, each stop would decay to a top quark and a neutralino, with the neutralino decaying primarily to a photon and gravitino. Shown above the the electron~+~jets or muon~+~jets final state of the top pair decay."

I also prefer the language of "top squark" over "stop quark" for clarity that it is not a quark. Somewhere else a comment was made that "stop squark" is redundant so I have edited those instances to be "top squark". The updated Figure 1 caption now reads:
"Feynman diagram of the GMSB scenario of interest. With top squarks as the lightest squark or gluino, their pair production would be the dominant production mechanism for SUSY in pp collisions at the LHC.

  • l 6: what is "a new little Hierarchy problem"? How does it differ from the known 'regular' hierarchy problem? Can you explain or give a reference?
