Abstract
In view of the start up of the 14 TeV pp Large Hadron Collider the quark anti-quark reactions leading to the final states W+W−, W±Z0 and Z0Z0 are studied, in the frame work of the Standard Model (SM), using helicity amplitudes. The differential and total cross sections are first evaluated in the parton anti-parton center of mass system. Subsequently they are transformed to their expected structure in pp collisions through the parton anti-parton Energy Density Functions which are here derived from the known Parton Density Functions of the proton. In particular the single and joint longitudinal polarizations of the di-boson final states are calculated. The effect on these reactions from the presence of s-channel heavy vector bosons, like the W' and Z', are evaluated to explore the possibility to utilize the gauge boson pair production as a probe for these 'Beyond the SM' phenomena.
