Description

The associated production of a Higgs boson with a single top quark provides direct access to measurement of the complex phase of the top Yukawa coupling. This process has not been observed yet. This work presents an evaluation of the sensitivity of the LHC experiments to this process during Run 3 and the upcoming High-Luminosity run. The analysis is based on a Monte Carlo simulation of signal and background taking into account typical features of LHC detectors.
