      abstract     = {In this dissertation, two different topics are addressed
                      which are vital for the realization of modern high-energy
                      physics experiments: detector development and data analysis.
                      The first part focuses on the development and
                      characterization of silicon pixel detectors. To account for
                      the expected increase in luminosity of the Large Hadron
                      Collider, the pixel detector of the Compact Muon Solenoid
                      (CMS) experiment will be replaced by an upgraded detector
                      with new front-end electronics. Comprehensive test beam
                      studies are presented which have been conducted to verify
                      the design and to quantify the performance of the new
                      front-end in terms of tracking efficiency and spatial
                      resolution. The tracking efficiency has been determined to
                      be 99.7 +0.3 $-0.5\%,$ while the spatial resolution has been
                      measured to be (4.80 +-0.29) um and (7.99 +-0.23) um along
                      the 100 um and 150 um pixel pitch, respectively.
                      Furthermore, a new cluster interpolation method is proposed
                      which utilizes the third central moment of the cluster
                      charge distribution and achieves improvements of the
                      position resolution of up to $40\%$ over the conventional
                      center of gravity algorithm. In the second part of the
                      thesis, an alternative measurement of the top quark mass is
                      presented. The mass is measured from the normalized
                      differential production cross sections of dileptonic top
                      quark pair events with an additional jet. The measurement is
                      performed on data recorded by the CMS experiment at $sqrt(s)
                      = 8$ TeV, corresponding to an integrated luminosity of 19.7
                      /fb. Using theoretical predictions at next-to-leading in
                      perturbative QCD, the top quark pole mass is measured to be
                      mt(pole) = 168.2 +4.7 -2.1 GeV with a precision of about
                      2.0\%. The measurement is in agreement with other
                      measurements of the top quark pole mass within the assigned
                      uncertainties.},
