Description
WHAT WE HAVE LEARNT FROM THE LHC HIGGS SEARCH? BASIC IDEA OF MEETING: Now that we have actually searched for and found a Higgs-like boson, we should have a small meeting to try to decide what we have learnt about the statistical issues involved, and to consolidate our experience. FORMAT: An informal framework of short introductions to various topics, followed by free discussion. READING MATERIAL: *  For the discovery of the Higgs(-like) object, the papers by ATLAS and by CMS are at      http://dx.doi.org/10.1016/j.physletb.2012.08.020 and http://dx.doi.org/10.1016/j.physletb.2012.08.021 * The CMS analysis that tries to determine the parity of the Higgs-like object is:  http://cds.cern.ch/record/1502670/files/cms-hig-12-041-arxiv.pdf  (see especially Fig 3) * The LEE papers papers by Eilam Gross and Ofer Vitells are: http://arxiv.org/abs/1005.1891(“Trial factors for the look elsewhere effect in high energy physics” ) http://arxiv.org/abs/1105.4355  (“Estimating the significance of a signal in a multidimensional search”) Also very useful for those interested in random fields is “Applications of random fields & Geometry” http://webee.technion.ac.il/people/adler/hrf.pdf (first few chapters from a book in progress) *  Higgs combination paper: http://cds.cern.ch/record/1375842?ln=en * Cranmer. Cowan, Gross and Vitells, 'Asymptotic formulae for likelihood-based tests of new physics', http://link.springer.com/article/10.1140%2Fepjc%2Fs10052-011-1554-0 This includes a description of 'Asimov data' Attendance by invitation only
