TITLE:
Unveiling the Mystery of Mass

ABSTRACT:

One of the prime reasons the Large Hadron Collider (LHC) was built is to 
resolve the question about how particles acquire their mass. While it is 
very simple to measure particle masses and we have a model – the Standard 
Model of Particle Physics -- which explains quite accurately all presently 
available measurements the seemingly trivial mechanism of how particles 
acquire their mass remains a mystery. The Standard Model invokes a new 
scalar gauge field to resolve this mystery but we have until very recently 
not been able to find experimental evidence for its existence. On July 4, 
2012, the CMS and ATLAS experiments have announced the discovery of a new 
Higgs-like particle at a mass of about 125 GeV. I will review our 
knowledge about the Higgs boson before the LHC started, quickly touch on 
the newest results from the Tevatron and discuss the discovery in this 
context. Finally, I will outline the steps required to complete the task 
and clearly identify the newly discovered particle as the Higgs boson.
