Journal ArticleDOI
The gauge-Higgs legacy of the LHC Run I
Anja Butter,Oscar J.P. Eboli,J. Gonzalez-Fraile,M. C. Gonzalez-Garcia,Tilman Plehn,Michael Rauch +5 more
TL;DR: In this article, the effects of new physics at the electroweak scale were studied using LHC data and the effective Lagrangian expansion (ELG) framework, and the results showed that the triple gauge vertices lead to a significant improvement in the entire set of operators describing Higgs couplings.
Journal ArticleDOI
Deep-learned Top Tagging with a Lorentz Layer
TL;DR: In this article, a new and highly efficient tagger for hadronically decaying top quarks, based on a deep neural network working with Lorentz vectors and the Minkowski metric, is introduced.
Journal ArticleDOI

TL;DR: In this article, a wide range of modern machine learning approaches were compared on the established task of identifying boosted, hadronically decaying top quarks, and they found that these new approaches are extremely powerful and great fun.

How to GAN LHC Events
TL;DR: In this paper, the maximum mean discrepancy is introduced to resolve sharp local features, which can be extended in a straightforward manner to include off-shell contributions, higher orders, or approximate detector effects.
