Idea is to investigate whether interference "dips" in mll can be used to enhance limits above bump hunting, using the Rivet implementation of the ATLAS 13 TeV mll spectrum + resolution smearing. | Idea is to investigate whether interference "dips" in mll can be used to enhance limits above bump hunting, using the Rivet implementation of the ATLAS 13 TeV mll spectrum + resolution smearing. | ||
Study dependence on resonance/interference width, play-off against measurement systematics, and propose recommendations on experimental data reporting to allow interference-aware interpretations in future. | Study dependence on resonance/interference width, play-off against measurement systematics, and propose recommendations on experimental data reporting to allow interference-aware interpretations in future. | ||

+ | Tasks: | ||
+ | * Richard & Yang: discuss models interesting for interference features | ||
+ | * Andy: implement fit-function normalisation, and re-fit to find correlations | ||
+ | * ALL: try model via MG5 with SM Drell-Yan interference; stats in Contur or standalone; ignore systematics (other than resolution smearing) for now | ||
