For instance, scientists need to use pi when calculating how "loops" -- particles that transform themselves into other particles, and then come back together to make the original particle again -- contribute to a particle's mass.

CNN: Scientists more certain that particle is Higgs boson

The search for Higgs got its biggest boost in December when researchers at the Large Hadron Collider, or LHC, near Geneva, Switzerland, said that data from two independent experiments had narrowed the range of the would-be particle's likely mass to between 124 and 126 gigaelectronvolts, or GeV.
