Feasibility Studies on the Measurement of Boosted Single Top Quark Production with the CMS Experiment — •Christopher Matthies, Roman Kogler, and Johannes Haller — Institut für Experimentalphysik, Universität Hamburg

Due to its unique properties, the top quark plays a key role in the search for physics beyond the Standard Model. Besides just being the heaviest elementary particle, its mean life time is significantly smaller than the usual time scale of hadronization processes. Thus, it can be surveyed as an isolated quark, allowing unique experimental studies.

At the LHC, only measurements of inclusive single top production cross sections have been performed so far. In this work, feasibility studies of measurements with highly boosted top quarks, with high transverse momentum, from single top quark production are presented. These processes provide stringent tests of the Standard Model predictions in the top sector and play an important role in searches for new physics with boosted top quarks in the final state. Additionally, such a measurement could help to constrain new physics models which predict particles with large couplings to top quarks.
