  1. Higgs to  at1.4 TeV update HEP Group , Vinča Belgrade I. Bozovic-Jelisavčić, G. Dumbelović, S. Lukić, M. Pandurović LCD-WG Analysis meeting 18. 04.2013.

  2. Signal pdf -Double-sided Gaussian - Composite Gaussian: exp. tail + - (5 parameters) flat tail (7 parameters) - used at 3TeV ( C.Grefe, PhD Thesis, Uni. Bonn, - only oneσ 2012 ,LCD Note-2011-035 ) - Better description of the shape • Likelihoodratio: ,Nevt= 9434 - Will make pull distribution for both to • compare LCD-WG Analysis Meeting 18th April 2013.

  3. Background pdf Separate fit of each background channel : - fit each background process individually - combine (AddPdf) - many processes to fit LCD-WG Analysis Meeting 18th April 2013.

  4. Background pdf- weighted unbinned likelihood fit of the overall background Alternative: - fit all backgrounds together - issue:normalization of different processes? - solution: use weighted dataset - normalization constant = weight wi LCD-WG Analysis Meeting 18th April 2013.
