Abstract
In this chapter, the top quark mass is measured from the normalized differential \(\mathrm{t}\bar{\mathrm{t}}\!+\)jet production cross section, which facilitates the direct comparison of the measurement with theoretical calculations without the need of a dedicated detector simulation or folding of the simulations to reconstruction level.
