Precise QCD Description of the Higgs Boson Transverse Momentum Spectrum / Chen, Xuan (U. Zurich (main)) ; Gehrmann, Thomas (U. Zurich (main)) ; Glover, E.W. Nigel (Durham U.) ; Huss, Alexander (CERN) ; Li, Ye (Fermilab) ; Neill, Duff (Los Alamos) ; Schulze, Markus (Humboldt U., Berlin) ; Stewart, Iain W. (MIT, Cambridge, CTP) ; Zhu, Hua Xing (Zhejiang U.)
The transverse momentum (

p_{T}

$p_T$ ) distribution of Higgs bosons at hadron colliders enables a detailed probe of its production dynamics and is a key ingredient to precision studies of Higgs boson properties, but receives very large QCD corrections. We obtain a precision prediction for the

p_{T}

$p_T$ spectrum by matching second-order (NNLO) QCD corrections at large

p_{T}

$p_T$ with resummation of third-order logarithmic (N

^{3}

$^3$ LL) corrections at small

p_{T}

$p_T$ . [...]

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

p p \to W^{+} W^{-} b \bar{b} \to (e^{+} ν_{e}) (μ^{-} {\bar{ν}}_{μ}) b \bar{b}

$pp\rightarrow W^+W^-b\bar b\rightarrow (e^+ \nu_e)\,(\mu^- \bar{\nu}_{\mu})\,b\bar b$ 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.

Constraining the top- $Z$ coupling through $t \bar t Z$ production at the LHC / Röntsch, Raoul (Fermilab) ; Schulze, Markus (CERN)
We study top pair production in association with a Z -boson at the LHC, focusing on the sensitivity to the top- Z couplings. As yet, these couplings have not been studied in a hadronic collider environment. [...]

Top quark mass determination from the energy peaks of b-jets and B-hadrons at NLO QCD / Agashe, Kaustubh (Maryland U.) ; Franceschini, Roberto (CERN) ; Kim, Doojin (Florida U.) ; Schulze, Markus (CERN)
We analyze the energy spectra of

s i n g l e

$single$ b-jets and B-hadrons resulting from the production and decay of top quarks within the SM at the LHC at the NLO QCD. For both hadrons and jets, we calculate the correlation of the peak of the spectrum with the top quark mass, considering the "energy-peak" as an observable to determine the top quark mass. [...]
