Tests of the SU(2) ⊗ U(1) gauge group from neutral current phenomena
Abstract
Cross section relations which provide tests of underlying SU(2) ⊗ U(1) gauge group are presented. The tests require the knowledge of the inclusive neutral current cross-sections σ ν p, σ overlineνp, σ ν nand σ overlineνn on proton and neutron targets. A particularly simple test is that the “sea” independent combinations ( σ ν p + σ overlineνp - σ ν n - σ overlineνn) and ( σ ν p - σ overlineνp - σ ν n + σ overlineνn) cannot both be positive. Ways of distinguishing between various SU(2) ⊗ U(1) models are also given.
