Sean Carroll Linda Randall – Higgs Sigma Deviations Page 71

page 179, 180 notes

quote

” If there is a Higgs at some specific mass, its main effect is to give a boost to the number of events we expect at the corresponding energy: a 125 GEV mass Higgs creates some extra particles with a total energy of 125 GEV, and so on.”

page 180

3 sigma deviation = evidence for something going on (0.3% of the time) 5 sigma deviation = discovery of something

December 2011

125 GEV = 3.6 sigma

ATLAS< 2.6 sigma in CMS

The International Conference on High Energy Physics (ICHEP)

John Ellis – theorist CERN

page 185 notes

ATLAS Higgs 126.5 GEV

CMS HIggs 125.3 GEV

= 5 sigma
