They found the Higgs Boson (using the scientific definition of discovery). That is what they were looking for. They also found it around the energy level they expected, and with the anticipated properties. I believe they also found an anomaly in the decay rate of the Boson, which they will investigate in the coming years.
I was referring to the mass of the Higgs boson. The discovery of the Higgs seems to be a triumphant validation of long suspected theories.. but at the same time created new problems as to others with the absence of equivalent energy.
