SMEFT analysis of high-pT dilepton tails, including angular observables

Participants Aoife Bharucha, Dario Buttazzo, Juhi Dutta, Berni Gaud, Tetiana Hrynova, David Marzocca, Marco Nardecchia, Giacomo Polesello, Priscilla Pani, Minho Son, Elena Venturi, Natascia Vignaroli, Tevong You

Tools:

• SMEFTsim (full SMEFT FeynRules model): https://feynrules.irmp.ucl.ac.be/wiki/SMEFT
• Our own FeynRules with the semileptonic, current-current, four-fermion dimension-6 operators.

Notes:

• List of operators: PDF

To do:

• Validate our UFO against other codes (e.g. SMEFTsim)
• List the parameter points required to build the complete EFT dependence of the signal
• Clarify the required simulations (only parton level, or also showering)
• Build the global likelihood and derive the fit
• Consider 13 TeV data
• Consider p p > l nu (limits on the triplet operators) and either study sensitivity prospects or recast data
