Description

Measurement of the production of a Higgs boson in association with a single top quark at ATLAS experiment is presented (https://arxiv.org/abs/2508.14695). The observed signal strength related to predicted by SM is μtH = 8.1 ± 2.6 (stat.) ± 2.0 (syst.).
Results of Machine Learning approaches, in particular Deep Neural Networks, with respect to event classification are discussed.
