Well this particle is making some noise these days.
Firstly, one of the most important physics of the history, Stephen Hawking, said that it doesn't exist. Nowadays, both Cern and the US Tevatron, have evidences of a possible Higgs boson.ñ
Firstly why is that particle so important?
The Higgs boson, is a key piece to prove the certanly of the Standard Physics Model, that model explains how the particle world works, if the Standard Model is true the physics world could change.
And why it is a key piece?
The higgs boson it's seems to be the responsible of the mass of the others particles, in common words, higgs create the mass to other particles.
So as I was saing, the Cern and the US tevatron have evidences, they cannot say that they've discovered the boson because they just have a 1% possiblity to fail but in my opinion quite soon will be an annouce for that dicovery
