The Higgs Boson and Electroweak Symmetry Breaking
... The Standard Model contains many fermions fields, a separate one for each left- or right-handed quark or lepton. A supersymmetric extension of the Standard Model therefore contains a huge number of elementary scalar fields. The mass terms for all of these fields are forbidden by the combination of t ...
