On the electroweak one-loop corrections

One-loop electroweak corrections are derived and analyzed by using a set of natural and convenient parameters. The ratio of masses of W- and Z-bosons, mW/mZ, and axial and vector couplings of leptonic Z-decays, gA and gV are considered as examples. In the framework of the Minimal Standard Model each of these quantities is presented as an explicit function of the masses of top quark, mt, and Higgs boson, mH, and of phenomenological parameter θ, which is expressed through a combination of the three quantities: mZ, α(mZ) and Gμ, which are known at present with much higher accuracy than other electroweak physical quantities.
