Study of the semi-boosted topology in top anti-top quark pair spectra

Abstract

The aim of this contribution is to present results of adding the semi-boosted transition region between the resolved and boosted top quark pair reconstruction in the $\ell$ + jets channel. This region is often omitted due to more complex reconstruction, which usually leads to a smaller efficiency. The reconstruction is performed for all three topologies for comparison and combination purposes. Hypothetical particle $Z^{\prime }$ was used as a probe to study the increase in the number of events in the studied energy region.
