SUSY cross sections and uncertainties for CMSSM (tanbeta=10, A0=0 and positive mu) grid used by ATLAS

A ROOT file is attached to this page with the cross sections and uncertainties for each m0 and m1/2 combination of this grid. The meaning of the variables inside the TTree is the following:

  • m0 : the m0 value of this entry.
  • m12 : the m1/2 value of this entry
  • crossSection : The (NLL+) NLO cross-section. (NLL+NLO if available)
  • Tot_error : The total (symmetric) uncertainty on the cross-section. This is a relative uncertainty.
  • mass1 : mass of the first particle in the final state pair. (e.g. : for squark-gluino (sg) production, mass1 = squark-mass)
  • mass2 : mass of the second particle in the final state pair. (e.g. : for squark-gluino (sg) production, mass2 = gluino-mass)
  • finalState : provides the information about the production process. This information is encoded in some integers. The corresponding meaning is given at the table below:

205 ~l^{-} - sneutrino  
206 stau1 - stau1  
207 stau2 - stau2  
208 stau1 - stau2  
209 sneutrino tau - sneutrino tau  
210 stau1^{+} - sneutrino tau  
211 stau1^{-} - sneutrino tau  
212 stau2^{+} - sneutrino tau  
213 stau2^{-} - sneutrino tau  

(*) Sbottom-pair production is included in the squark-antisquark production. For models sensitive to b1b1 or b2b2, these values should be used and the squark-antisquark production cross section should be rescaled down by 4/5.

Note that there are no numbers for gaugino-gaugino interactions as they have not been considered for this particular grid. The reason is that this grid is generally used for the interpretation of strong production analyses, which have little sensitivity to these processes.
