WG2: Event Simulations and Monte Carlo Tools

Polarization of vector bosons started to become an extensively investigated topic in recent years due to its sensitivity to the concrete mechanism of electroweak symmetry breaking and to beyond standard model physics. The general-purpose Monte-Carlo event generator Sherpa is used for event simulation of various processes in the analysis of LHC data. In this talk, an implementation is presented...

WG8: QCD for BSM studies

In the Standard Model (SM) of particle physics, four-top-quark production is an extremely rare process with a cross section of approximately 12 fb. In extensions of the SM with top-philic new states, the four-top production rate can be enhanced considerably. In this contribution results will be presented of searches by the ATLAS and CMS experiments that have yielded the first evidence for the...

133. Learning to integrate

WG2: Event Simulations and Monte Carlo Tools

In this contribution I will describe a method to perform multi-dimensional paramtric integrations by fitting a neural network to integrand data. THis method can be applied to many areas in QCD, from phase-space integration to multi-loop integrals.
