ODSL Forum: Anja Butter, Back to the Formula — LHC Edition

Friday 18 Feb 2022, 14:00 → 15:00 Europe/Berlin

Presenter: Anja Butter,  University of Heidelberg
Title: Back to the Formula — LHC Edition

Abstract:

While neural networks offer an attractive way to numerically encode functions, actual formulas remain the language of theoretical particle physics. We use symbolic regression trained on matrix-element information to extract, for instance, optimal LHC observables. This way we invert the usual simulation paradigm and extract easily interpretable formulas from complex simulated data. We introduce the method using the effect of a dimension-6 coefficient on associated ZH production. We then validate it for the known case of CP-violation in weak-boson-fusion Higgs production, including detector effects.

As usual, the format will be a short presentation followed by plenty of discussion.

Please let all interested know about the Journal Club (get them to send their Email address).  We are looking forward to lively discussions.
