Streszczenie: In order to verify the successful Standard Model of elementary physics, described
by the interplay of strong and electroweak interactions, and in order to find out
whether or not extensions of this model are necessary, high precision measurements
of particle creation and decay processes performed at facilities like the Large Hadron
Collider at CERN have to be compared with theory predictions that are of the
same precision. The precision and significance of theory predictions can be improved
in two ways, namely by taking into account exchanges of virtual particles in the
framework of higher order perturbative corrections to a given process, known as
radiative corrections, or by looking at observables that characterise the process in a
more precise way. One for instance can take into account the masses of the particles
that participate in the process, or look at effects of polarisation in the process
