A Plausibility Semantics for Abstract Argumentation Frameworks

We propose and investigate a simple ranking-measure-based extension semantics for abstract argumentation frameworks based on their generic instantiation by default knowledge bases and the ranking construction semantics for default reasoning. In this context, we consider the path from structured to logical to shallow semantic instantiations. The resulting well-justified JZ-extension semantics diverges from more traditional approaches.Comment: Proceedings of the 15th International Workshop on Non-Monotonic Reasoning (NMR 2014).

Charged Higgs production with a top in MC@NLO

The production in association with a top quark is the most promising search channel for charged Higgs bosons at the LHC. We review its theoretical description including next-to-leading order corrections and the combination with a parton shower. The latter allows us to for the first time answer questions about the kinematics of all jets in the process. We then describe the consistent subtraction of intermediate states and present new results about the bottom mass uncertainty impacting the parton densisities.Comment: Proceedings `Prospects for Charged Higgs Discovery at Colliders', including new results on bottom mass induced uncertainty, on-shell subtraction, and reference cross section

Associated production of top quarks and charged Higgs bosons at next-to-leading order

Accurate predictions for both signal and background events at the LHC are of paramount importance in order to confirm even the smallest deviations from Standard Model predicitions. Next-to-leading order Monte Carlo event generators are an essential tool to reach that goal. Concerning the charged Higgs boson, NLO calculations of the production cross section already exist. Reiterating the calculation using a subtraction formalism enables us to implement the cross section into Monte Carlo generators, which can then be used by experiments

Epistemic Norms in a Nutshell

We present some thoughts on epistemic norms

Ranking Revision Reloaded

In the context of a general revision framework, we propose and take a first look at revision strategies for epistemic ranking measures reaching beyond minimal Jeffrey-conditionalization, a variant of Spohn-style revision
