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 , with a mass distinct from that of the Higgs boson, decaying into four leptons ( , ) via an intermediate state contai…

Measurement of top-quark pair production in association with charm quarks in proton-proton collisions at TeV with the ATLAS detector
ATLAS Collaboration
Inclusive cross-sections for top-quark pair production in association with charm quarks are measured with proton-proton collision data at a center-of-mass energy of 13 TeV correspo…

Measurement of the associated production of a top-antitop-quark pair and a Higgs boson decaying into a pair in collisions at TeV using the ATLAS detector at the LHC
ATLAS Collaboration
This paper reports the measurement of Higgs boson production in association with a pair in the decay channel. The analysis uses 140 fb o…
