In this thesis two different aspects of Standard Model Higgs boson phenomenology at hadron colliders are addressed. A precise theoretical knowledge of production cross sections is needed in order to assist in the Higgs boson search efforts of the experimental community. Consequently, the next-to-leading-order electroweak corrections to Higgs boson production in association with a vector boson at hadron colliders have been calculated. Significant corrections were found, and theoretical uncertainties were analysed. In addition to production cross sections, a deep knowledge of background processes is also needed, especially at hadron colliders. The gluon-induced contributions to offshell W-boson pair production have been calculated. The invariant amplitude has been used to calculate the contribution from gluon initiated processes to the non-resonant W-boson pair production background to the Higgs boson search channel at the CERN LHC. These contributions are evaluated in the approximation of massless quarks circulating the loops. These results were used to study the effect of experimental cuts proposed to increase the signal to background ratio of the above mentioned search channel.
