the idea girl says
coupling loops of particles to Higgs Boson and Photons
in “The Standard Model itself, this rate is completely fixed once we now the Higgs mass.
Standard Model = Fixed Rate = Known M+ mass of = O Higgs Boson +M
O Higgs + Mass known –> Decays different (faster) = unseen existence of new particles
LHC Data 2011 – early 2012 more photons produced than the Standard Model predicts.
