Effective operators in $t$-channel single top production and decay
/ de Beurs, M. (Nikhef, Amsterdam) ; Laenen, E. (Nikhef, Amsterdam ; Amsterdam U. ; Utrecht U.) ; Vreeswijk, M. (Nikhef, Amsterdam) ; Vryonidou, E. (Nikhef, Amsterdam ; CERN)
The production of a single top quark in the $t$-channel and its subsequent decay is studied at NLO accuracy in QCD, augmented with the relevant dimension-6 effective operators from the Standard Model Effective Theory. We examine various kinematic and angular distributions for proton-proton collisions at the LHC at 13 TeV, in order to assess the sensitivity to these operators, both with and without the top quark narrow width approximation.

(MIT, Cambridge, CTP) ; Lopez-Villarejo, Juan J. (CEA, DSM, Saclay ; CERN ; Madrid, Autonoma U.) ; Ritzmann, Mathias (CEA, DSM, Saclay) ; Skands, Peter (CERN)
We summarize recent developments in the VINCIA parton shower. After a brief review of the basics of the formalism, the extension of VINCIA to hadron collisions is sketched. [...]

Antenna Showers with One-Loop Matrix Elements
/ Hartgring, L (NIKHEF, Amsterdam) ; Laenen, E (NIKHEF, Amsterdam ; Amsterdam U. ; Utrecht U.) ; Skands, P (CERN)
We consider the probability for a colour-singlet qqbar pair to emit a gluon, in strongly and smoothly ordered antenna showers. We expand to second order in alphaS and compare to the second-order QCD matrix elements for Z -> 3 jets, neglecting terms suppressed by 1/NC^2. [...]

On next-to-eikonal exponentiation
/ Laenen, Eric (NIKHEF, Amsterdam ; Utrecht U. ; Amsterdam U.) ; Magnea, Lorenzo (CERN ; Turin U. ; INFN, Turin) ; Stavenga, Gerben (Fermilab) ; White, Chris D. (Durham U., IPPP)
The eikonal approximation is at the heart of many theoretical and phenomenological studies involving multiple soft gauge boson emissions in high energy physics. We describe our efforts towards the extension of the eikonal approximation for scattering amplitudes to the first subleading power in the soft momentum..

Supersymmetric top and bottom squark production at hadron colliders
/ Beenakker, Wim (Nijmegen U., IMAPP) ; Brensing, Silja (Aachen, Tech. Hochsch. ; NIKHEF, Amsterdam) ; Kramer, Michael (CERN ; Aachen, Tech. Hochsch.) ; Kulesza, Anna (Aachen, Tech. Hochsch.) ; Laenen, Eric (Amsterdam U. ; Utrecht U. ; NIKHEF, Amsterdam) ; Niessen, Irene (Nijmegen U., IMAPP)
The scalar partners of top and bottom quarks are expected to be the lightest squarks in supersymmetric theories, with potentially large cross sections at hadron colliders. We present predictions for the production of top and bottom squarks at the Tevatron and the LHC, including next-to-leading order corrections in supersymmetric QCD and the resummation of soft gluon emission at next-to-leading-logarithmic accuracy.

Charged Higgs boson production in association with a top quark in MC@NLO
/ Weydert, C. (LPSC, Grenoble) ; Frixione, S. (CERN ; LPHE, Lausanne) ; Herquet, M. (NIKHEF, Amsterdam) ; Klasen, M. (LPSC, Grenoble) ; Laenen, E. (NIKHEF, Amsterdam ; Amsterdam U. ; Utrecht U.) ; Plehn, T. (Heidelberg U.) ; Stavenga, G. (Utrecht U. ; Fermilab) ; White, C.D. (Durham U., IPPP)
We discuss the calculation of charged Higgs boson production in association with top quark in the MC@NLO framework for combining NLO matrix elements with a parton shower. The process is defined in a model independent manner for wide applicability, and can be used if the charged Higgs boson mass is either greater or less than the mass of the top quark. [...]
