Query: Fast supersymmetry phenomenology at the Large Hadron Collider using
  machine learning techniques   A pressing problem for supersymmetry (SUSY) phenomenologists is how to
incorporate Large Hadron Collider search results into parameter fits designed
to measure or constrain the SUSY parameters. Owing to the computational expense
of fully simulating lots of points in a generic SUSY space to aid the
calculation of the likelihoods, the limits published by experimental
collaborations are frequently interpreted in slices of reduced parameter
spaces. For example, both ATLAS and CMS have presented results in the
Constrained Minimal Supersymmetric Model (CMSSM) by fixing two of four
parameters, and generating a coarse grid in the remaining two. We demonstrate
that by generating a grid in the full space of the CMSSM, one can interpolate
between the output of an LHC detector simulation using machine learning
techniques, thus obtaining a superfast likelihood calculator for LHC-based SUSY
parameter fits. We further investigate how much training data is required to
obtain usable results, finding that approximately 2000 points are required in
the CMSSM to get likelihood predictions to an accuracy of a few per cent. The
techniques presented here provide a general approach for adding LHC event rate
data to SUSY fitting algorithms, and can easily be used to explore other
candidate physics models.
