KISMET: MSSM Likelihood Samples

These samples were obtained by the KISMET method (Killer Inference in Susy METeorology). For access to samples of the phenomenological (pMSSM) data used in arXiv:0906.0957, please email Shehu AbdusSalam shehu@ictp.it.

Alternatively, for CMSSM samples, use: arXiv:0705.0487. If you use them, please cite that paper. You might also like to look at the preceeding papers on the same topic: [1 | 2 | 3]. The SLHA files come from independent samplings of the MCMC samples that they are listed with.

[ Tarred gzipped files | root file | SLHA format files ]:

When you untar the file (via tar -xvzf), you should end up with 10 independent files. Each one is a statistically independent sampling of the posterior.

The density of points in parameter space is proportional to the posterior probability of the point. The fits are described in the paper, and have had the dark matter, (g-2)_mu, B_s->mu mu, MW, sin^2 theta_l, mt, mb, alphas, BR(b->s gamma) and sparticle/Higgs direct search limits applied to them. Each point in the sample is a line of the file, organised into a list of numbers, in the following order:

  1. The weight of the point - you *must* take this into account if you're doing Bayesian stats.
  2. An integer specifying the number of parameters to come
