Search for heavy resonances in the decay channel 𝑾+𝑾− → 𝒆𝝂𝝁𝝂 in 𝒑 𝒑 Collisions at √𝒔 = 13 TeV using 139 fb−1 of data with the ATLAS detector

A search for neutral heavy resonances (𝑅) is made in the 𝑊+𝑊− → 𝑒𝜈𝜇𝜈 decay channel using 𝑝𝑝 collision data corresponding to an integrated luminosity of 139 fb−1, collected at a centre-of-mass energy of 13 TeV by the ATLAS detector at the CERN Large Hadron Collider. No evidence of any heavy resonances is found. Upper limits on 𝜎𝑅 × 𝐵𝑅(𝑅 → 𝑊𝑊) are obtained as a function of the resonance mass ranging from 300 GeV to 4 TeV for five different models: a Higgs-like narrow width scalar, a Higgs boson in the Georgi–Machacek model, a radion particle arising in the bulk Randall-Sundrum model, a spin-1 heavy vector triplet, and a spin-2 graviton, all with the resonance produced through either gluon-gluon fusion, quark-antiquark annihilation, or vector-boson fusion.
