Test of $C P$ Invariance in Higgs Boson Vector-Boson-Fusion Production Using the $H \to I^^{3} I^^{3}$ Channel with the ATLAS Detector

ATLAS Collaboration

A test of $C P$ invariance in Higgs boson production via vector-boson fusion has been performed in the $H \to I^^{3} I^^{3}$ channel using 139 fb $^{- 1}$ of proton-proton collision data…

Search for a new scalar decaying into new spin-1 bosons in four-lepton final states with the ATLAS detector

ATLAS Collaboration

A search is conducted for a new scalar boson $S$ , with a mass distinct from that of the Higgs boson, decaying into four leptons ( $ℓ =$ $e$ , $I^¼$ ) via an intermediate state conta…

Search for single production of vector-like $T$ quarks decaying into $H t$ or $Z t$ in $pp$ collisions at $s = 13$ TeV with the ATLAS detector

ATLAS Collaboration

This paper describes a search for the single production of an up-type vector-like quark ( $T$ ) decaying as $T \to H t$ or $T \to Z t$ . The search utilises a dataset of…
