Experimental tests and theoretical predictions for electroweak processes

In sect. 2, I will briefly recall the basic ingredients of the standard model and I will define the relevant parameters. Low-energy processes which enter into the determination of neutral-current couplings to fermions (in particular sin 2θW) are presented in sect. 3. Radiative corrections to these processes are discussed in sect. 4. In sect. 5 the measurements of the W and Z0 masses at the SPS collider are described and compared with theoretical predictions including one-loop radiative corrections. (orig./BBO)
