Soft Gluon Resummation for the Associated Single Top and Higgs Production at the LHC — •Laura Moreno Valero, Anna Kulesza, and Daniel Schwartländer — Institut für Theoretische Physik, Westfälische Wilhelms Universität Münster, Deutschland

Processes involving the Higgs boson and the top quark are of high interest in searches for BSM physics as a way to directly access the top Yukawa coupling. Although it has a relatively small cross section, the single top and Higgs production process pp → Htj is particularly sensitive to new physics, calling for precise theoretical predictions. A reduction of theoretical uncertainties can be achieved by means of resummation techniques, accounting for large logarithmic corrections which originate from soft gluon emissions. In this talk we discuss extending the precision with which theoretical predictions for this process are known from NLO (next-to-leading order) to NLO+NLL (next-to-leading logarithmic matched to NLO) accuracy.
