Probing the CP structure of the top quark Yukawa coupling: Loop sensitivity vs. on-shell sensitivity
Till Martini, Ren-Qi Pan, Markus Schulze +1
The question whether the Higgs boson is connected to additional CP violation is one of the driving forces behind precision studies at the Large Hadron Collider. In this work, we in…
The Matrix Element Method as a tool for precision and accuracy
Till Martini, Manfred Kraus, Sascha Peitzsch +1
The Matrix Element Method is a promising multi-variate analysis tool which offers an optimal approach to compare theory and experiment according to the Neyman-Pearson lemma. Howeve…
Electroweak Loops as a Probe of New Physics in Production at the LHC
Till Martini, Markus Schulze
We calculate the weak corrections to top quark pair production at the LHC and include anomalous electroweak interactions from dimension-six operators. The loop cal…
Exploring BSM Higgs couplings in single top-quark production
Manfred Kraus, Till Martini, Sascha Peitzsch +1
In this article we study a Standard Model extension modifying the top-quark Yukawa coupling to the Higgs boson by allowing a mixture of CP-odd and -even couplings. Single top-quark…
Matrix Element Method at NLO for (anti-)-jet algorithms
Manfred Kraus, Till Martini, Peter Uwer
In this article, we present a method to calculate a posteriori event weights at next-to-leading-order (NLO) QCD accuracy for a given jet event defined by the (anti-) algorithm…
The Matrix Element Method at next-to-leading order QCD using the example of single top-quark production at the LHC
Till Martini
Analyses in high energy physics aim to put the Standard Model---the commonly accepted theory---to test. For convincing conclusions, analysis methods are needed which offer an unamb…
