But scientists do not know if the particle they've found is truly the one predicted by the Standard Model of particle physics.

Nonetheless, it remains to be seen whether the new particle is the Higgs boson of the standard model, or one of several other bosons predicted by other theories of physics.

For example, the rate at which the new particle is produced seems to be slightly higher than the one predicted in the Standard Model.
