Mostrar otras versiones (1)

A search for $W^{\prime}$ production with decay to a top quark and a bottom quark in proton-proton collisions at $\sqrt{s}$=13 TeV with the ATLAS detector is presented. The hadronic decay of the top quark is identified using DNN-based boosted-object techniques. The dominant background is obtained by...

description A search for $W^{\prime}$ production with decay to a top quark and a bottom quark in proton-proton collisions at $\sqrt{s}$=13 TeV with the ATLAS detector is presented. The hadronic decay of the top quark is identified using DNN-based boosted-object techniques. The dominant background is obtained by a data-driven method with small systematic uncertainties. The results are presented as upper limits on the $W^{\prime}$ production cross-section times the top-bottom channel branching ratio for several $W^{\prime}$ masses ranging from 1.5 to 5 TeV.

The search focuses on the decay of the $W^{\prime}$ to a hadronic top quark and a bottom quark, using the full Run 2 dataset of the ATLAS detector. The hadronic decay of the top quark is identified using DNN-based boosted-object techniques. The dominant background is obtained by a data-driven method with small systematic uncertainties. The results are presented as upper limits on the production cross-section times decay branching ratio for the $W^{\prime}$ boson with right-handed couplings that decays to a top quark and a bottom quark, for several $W^{\prime}$ masses between 1.5 to 5 TeV.arXiv:2201.10343ATL-PHYS-PROC-2022-010ATL-PHYS-PROC-2021-088oai:cds.cern.ch:27891032021-10-29
