Second Z-boson and electroweak mixing angle

Creators

Description

The cross-section ratio of neutral-current neutrino scattering on nucleons in models with one (standard model) and two Z-bosons is calculated. Its value is found to be ∼ 1.15 for the mass m2 of Z2-boson being m2 ∼ 200 GeV (the modern lower boundary for m2). Obtained more severe restriction on m2:m2 >or approx. 500-700 GeV
