Is the Higgs boson already found?

what EXACTLY is the Higg's boson?

Kind of a gauge theory patch, nothing else.

what EXACTLY is the Higg's boson?

The Higgs boson is a theoretical particle required by the Higg's mechanism. The Higg's mechanism is a way to mathematically add mass to the present theory and thus may solve the gauge invariance problem.

You can always get general information from wikipedia http://en.wikipedia.org/" but you do have to be carefull. Some inaccruacies go uncorrected.

For example
"The Higgs mechanism in the standard model successfully predicts the mass of the W±, and Z weak gauge bosons, which are naturally massless."

The Higgs mechanism does not in fact predict the mass of the W±, and Z weak gauge bosons as the Higgs mechanism does not predict the coupling value between the Higgs field and the W±, and Z bosons.

In fact using the data from the W and Z bosons indicates the most likely mass for the Higgs boson is about the same as the Z boson. This means the Higgs boson should have already been found!
