Did the LHC discover the Higgs?
On December 13, at the end of the 2011 running year, both
the ATLAS and the CMS collaborations made their Higgs search results
public in a single joint seminar. The two collaborations laid out their
multichannel analyses in what seemed like an endless set of statistical
statements. Furthermore, the reluctance to provide a"yes-or-no" answer
fueled some journalists to report the discovery of the "god particle"
while other decided that the LHC has rejected the Higgs mechanism. In
view of this confusion, I will discuss the results shown at CERN but
not before an introduction to the topic will be presented. A
description of the Higgs mechanism and the Standard Model need
for it will be followed by an explanation of the search for the Higgs
particle and the statistical statements made.
