Description
A search for a fermi-phobic heavy Higgs boson via the $pp \rightarrow W^{\pm}H \rightarrow W^{\pm}W^{\pm}W^{\mp}$ process with 139 fb$^{-1}$ of $pp$ collision data at $\sqrt{s}=13~\text{TeV}$ collected by the ATLAS detector is presented.
The heavy Higgs boson has potential dimension-6 effects in an effective field theory context, which can cause significant kinematic deviations from those predicted within the Standard Model. Events with two same-sign leptons ($e$ or $\mu$) in association with one large-R jet or two small-R jets with an invariant mass consistent with a hadronically decaying $W$-boson are analyzed to test for the presence of effects from new physics.
