SModelS stores all the information about the experimental results in an analyses database [*]. The database is organized as files in an ordinary (UNIX) directory hierarchy, with a thin python layer serving as the access to the database.
The top level of the SModelS database categorizes the analyses by LHC center-of-mass energies, \(\sqrt{s}\):
Also, the top level directory contains a file called version with the version string of the database.
The second level splits the results up between the different experiments:
The third level of the directory hierarchy encodes the publications:
For each publication, there are two files:
sqrts: 8.0*TeV
lumi: 19.5/fb
id: CMS-SUS-13-006
url: https://twiki.cern.ch/twiki/bin/view/CMSPublic/PhysicsResultsSUS13006
arxiv: http://arxiv.org/abs/1405.7570
publication: http://link.springer.com/article/10.1140%2Fepjc%2Fs10052-014-3036-7
supersedes: CMS-PAS-SUS-12-022
digitaldata: True
In particular, it defines the center-of-mass energy \(\sqrt{s}\) (in TeV) and the integrated luminosity, \(\mathrm{fb}^{-1}\). Optionally, units (e.g. “* TeV” or “/ fb”) can be added to the number.
The next block:
constraint: TChiWZ -> [[['W']],[['Z']]]
constraint: TSlepSlep -> [[['e+']],[['e-']]]+[[['mu+']],[['mu-']]]
fuzzycondition: TChiWZ -> None
fuzzycondition: TSlepSlep -> Cgtr([[['mu+']],[['mu-']]],[[['e+']],[['e-']]])
holds the constraint and conditions, as described in constraint, and conditions, respectively.
Finally,
axes: TChiWZ: M1 M0, TSlepSlep: M1 M0, TChiChipmSlepL: M1 M0 050 - M1 M0 005 - M1 M0 095, TChiChipmSlepStau: M1 M0 050 - M1 M0 005 - M1 M0 095,TChiWZoff: M1 M0, TChiWH: M1 M0
describes the mass planes and how for analyses with intermediate masses, the two-dimensional histograms map onto the three-dimensional SMS parameter space.
