"abstract": "<p>In this thesis, the investigation of the cross section ratio of two established processes<br>\noccurring in proton-proton collisions is performed. This choice is motivated by the fact,<br>\nthat the comparison of two separate measurements in the form of cross section ratios<br>\npromises to benefit from reduced uncertainties.<br>\nThe first observable of interest is the inclusive dijet cross section. Dijet events are occurring<br>\nat high rates at the LHC, due to the abundant production of jets at hadron colliders.<br>\nInvestigation of the dijet spectrum allows for tests of QCD, as the particles within the jets follow the laws of the strong nuclear force. Furthermore, these QCD events are<br>\nthe background for many other physics searches, and consequently have to be precisely<br>\nunderstood in order to increase the accuracy of other measurements. Another advantage<br>\nof the dijet event topology is the fact that it covers a wide kinematic range.<br>\nThe second process of choice is the inclusive Z+jet cross section. The Z boson has been<br>\nstudied in various experiments and its properties are very well known. This process allows<br>\nfor precise measurements, because it leaves a clear signal in the detector. Together with<br>\nthe leading jet in the Z+jet event, this final state can be studied in an analogous manner<br>\nas the dijet final state.<br>\n </p>",
