#lepton flavour universality

Measurement of high-mass $t\bar{t}{\ell }^{+}{\ell }^{-}$ production and lepton flavour universality-inspired effective field theory interpretations at $\sqrt{s}=13$ TeV with the ATLAS detector

ATLAS Collaboration

The ATLAS experiment measured the production of top‑antitop pairs with a high‑mass lepton pair (tt̄ℓ⁺ℓ⁻) using 13 TeV proton‑proton collisions, examined lepton‑flavour universality…
