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
