$ZH$ production in gluon fusion: two-loop amplitudes with full top quark mass dependence / Chen, Long (Munich, Max Planck Inst. ; Aachen, Tech. Hochsch.) ; Heinrich, Gudrun (KIT, Karlsruhe, TP) ; Jones, Stephen P. (CERN ; Durham U., IPPP) ; Kerner, Matthias (Zurich U.) ; Klappert, Jonas (RWTH Aachen U.) ; Schlenk, Johannes (PSI, Villigen)
We present results for the two-loop helicity amplitudes entering the NLO QCD corrections to the production of a Higgs boson in association with a $Z$-boson in gluon fusion. The two-loop integrals, involving massive top quarks, are calculated numerically. [...]

Photon pair production in gluon fusion: Top quark effects around threshold / Chen, Long (Munich, Max Planck Inst.) ; Heinrich, Gudrun (Munich, Max Planck Inst.) ; Jahn, Stephan (Munich, Max Planck Inst.) ; Jones, Stephen P. (CERN) ; Kerner, Matthias (Zurich U.) ; Schlenk, Johannes (PSI, Villigen) ; Yokoya, Hiroshi (Korea Inst. Advanced Study, Seoul)
We present a calculation of the NLO QCD corrections to the loop-induced production of a photon pair through gluon fusion, including massive top quarks at two loops. The two-loop virtual amplitudes are computed via projecting onto a set of Lorentz structures related to linear polarisation states of external gauge bosons. [...]

Photon pair production in gluon fusion: Top quark effects at NLO with threshold matching / Chen, Long (Munich, Max Planck Inst.) ; Heinrich, Gudrun (Munich, Max Planck Inst.) ; Jahn, Stephan (Munich, Max Planck Inst.) ; Jones, Stephen P. (CERN) ; Kerner, Matthias (Zurich U.) ; Schlenk, Johannes (PSI, Villigen) ; Yokoya, Hiroshi (Korea Inst. Advanced Study, Seoul)
We present a calculation of the NLO QCD corrections to the loop-induced production of a photon pair through gluon fusion, including massive top quarks at two loops, where the two-loop integrals are calculated numerically. Matching the fixed-order NLO results to a threshold expansion, we obtain accurate results around the top quark pair production threshold. [...]

NLO and off-shell effects in top quark mass determinations / Heinrich, G. (Munich, Max Planck Inst.) ; Maier, Andreas (CERN) ; Nisius, Richard (Munich, Max Planck Inst.) ; Schlenk, Johannes (Durham U., IPPP) ; Schulze, Markus (Humboldt U., Berlin) ; Scyboz, Ludovic (Munich, Max Planck Inst.) ; Winter, Jan (Michigan State U.)
We study the impact of different theoretical descriptions of top quark pair production on top quark mass measurements in the di-lepton channel. To this aim, the full NLO corrections to $pp\rightarrow W^+W^-b\bar b\rightarrow (e^+ \nu_e)\,(\mu^- \bar{\nu}_{\mu})\,b\bar b$ production are compared to calculations in the narrow width approximation, where the production of a top quark pair is calculated at NLO and combined with three different descriptions of the top quark decay: leading order, next-to-leading order and via a parton shower.
