Study of Double Parton Scattering Using Four-Jet Scenarios: in Proton-Proton Collisions at sqrt s = 7 TeV with the CMS Experiment at the LHC

This thesis addresses in a very new and elegant way several measurements and the extraction of so-called double parton scattering. The new and elegant way lies in the combination of measurements and a very smart extraction of double parton scattering results, which is easy to apply and overcomes many of the technical difficulties of older methods. Many new phenomena in particle physics can be observed when particles are collided at the highest energies; one of the highlights in recent years...
