Todo for next SModelS version (2.0.1 or 2.1.0):

• modelTester mode that returns all datasets
• validation mode that writes out next-to-best SRs
• combination that runs with missing txname files
• add new xsec computers

Student Projects

• MSSM EW-ino scan

  • to what extent can we improve coverage [of mixed scenarios] by combining likelihoods from different analyses?

  • need EMs for all the leading EW searches --> recasting

• IDM scenario : add EMs for TChiZ topology from EW SUSY (chargino, neutralino, slepton) and Higgs->inv analyses; can we cover the low mass region with prompt decays?

• Implement joint likelihoods in SModelS (add feature for analyses correlation matrix)

  • Numerical maximization of "heterogeneous" joint likelihoods

  • Copula functions may be used to model correlations between analyses

• Aggregation algorithms

  • Set small correlations to zero:

    1. do we gain in CPU performance?

    2. up to what size may one neglect correlations before loosing in precision?

    3. try to split off SRs with small correlations from large covariance matrix to get a smaller cov.M times product of approx. uncorrelated likelihoods

  • try different types of distance measures (min, max, mean) between sets of SRs

  • think about using Fisher information for aggregation
