Differential Cross Sections for Top-Quark-Pair Production in the e/$\mu$+Jets Final State at $\sqrt{s} = 8$ TeV in CMS / Goerner, Martin (Hamburg U.) ; Schleper, Peter (dir.) (Hamburg U.)
The large number of top quarks produced in proton-proton (pp) collisions at the LargeHadron Collider facilitates precision measurements of top-quark properties that are crucialfor testing the consistency of the Standard Model (SM) of particle physics. In particular,differential measurements of the top-quark pair (tt) production cross section are essentialfor comparison with state-of-the-art predictions of Quantum Chromodynamics (QCD)within the SM and for searches for new physics phenomena beyond it. [...]

Measurement of Top-Quark Mass and Inclusive Top-Quark-Pair Production Cross Section in pp Collisions at $\sqrt{s} = 7/8$ TeV with CMS / Schlieckau, Eike Steffen (Hamburg U.) ; Schleper, Peter (dir.) (Hamburg U.)
One of the most intriguing particles in the Standard Model is the top quark, theheaviest fundamental particle known to date. In this thesis, the mass of the top quarkand the production cross section for top-quark pairs are measured from events with atop-quark pair decaying only into hadrons. [...]
