Constraints on the Higgs boson self-coupling from the combination of single-Higgs and double-Higgs production analyses performed with the ATLAS experiment
Constraints on the Higgs boson self-coupling are set by combining the single Higgs boson analyses targeting the $\gamma \gamma$, $ZZ^*$, $WW^*$, $\tau^+ \tau^-$ and $b\bar{b}$ decay channels and the double Higgs boson analyses in the $b\bar{b}b\bar{b}$, $b\bar{b}\tau^+\tau^-$ and $b\bar{b} \gamma \gamma$ decay channels, using data collected at $\sqrt{s} = 13$ TeV with the ATLAS detector at the LHC.

Measurement of the top quark mass using a leptonic invariant mass in pp collisions at $sqrt{s}$ = 13 TeV with the ATLAS detector
A measurement of the top quark mass ($m_t$) in the $t\bar{t}\rightarrow~\textrm{lepton}+\textrm{jets}$ channel is presented, with an experimental technique which exploits semileptonic decays of $b$-hadrons produced in the top-quark decay chain. [...]
