On July 4th 2012 CERN scientists announced that two independent experiments, CMS and ATLAS had detected a new particle of nature. This kind of discovery does not come along all that often and so it naturally led to an explosion of interest in the press and media as well as amongst physicists throughout the world.
Is it the Higgs or something else resembling a Higgs?
This talk will explain why a Higgs-like particle is required to complete the standard model of particle physics, the matter and forces which affect all of us. I will describe the incredible precision and energies associated with the LHC accelerator which allows the amazing detectors like CMS and ATLAS to observe sufficient events allow- ing the groups to announce this new particle. If it is a Higgs it completes the picture but it brings with it many unanswered questions which we will discuss. If it isn't the Higgs, then what could it be?
