Task: Text Categorization
Input (English): This particle is produced along with a muon, and antimuon by the collision of an electron and a positron in the Bjorken process. This particle's decay into two tau leptons has not yet been observed, casting doubt on its postulated spin of zero. This elementary particle was initially hypothesized to explain, through spontaneous symmetry breaking, why the W and Z bosons are massive, and we now know that its namesake field is what imparts mass to matter. It is a target of the Large Hadron Collider. For 10 points, name this no-longer-hypothetical boson discovered in 2012, nicknamed the "God particle".
Output (English): Science
