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.},
