Trigger Menu in 2017
This document summarises the trigger menu deployed by the ATLAS experiment during 2017 data taking at proton-proton collision centre-of-mass energies of $\sqrt{s}=13$ TeV and $\sqrt{s}=5$ TeV at the LHC and describes the improvements with respect to the trigger system and menu used in 2016 data taking..

Study of multiple hard-scatter processes from different p p interactions in the same ATLAS event
Given the large integrated luminosity and the large average pileup in the 2017 ATLAS dataset, the probability of having two leptonically decaying Z bosons originating from separate $pp$ interactions in the same LHC bunch crossing becomes non-negligible. [...]

Prospects for the measurement of the rare Higgs boson decay $H\to\mu\mu$ with 3000 fb$^{-1}$ of $pp$ collisions collected at $\sqrt{s} = 14$ TeV by the ATLAS experiment
This note presents a study of the prospects for the measurement of the rare Higgs boson decay $H\to \mu\mu$ using 3000 fb$^{-1}$ of proton-proton collisions at $\sqrt{s}=14$ TeV recorded with the ATLAS detector at the high-luminosity LHC. [...]

Prospects for the $\cal{B}$$(B^0_{(s)} \to \mu^+ \mu^-)$ measurements with the ATLAS detector in the Run 2 and HL-LHC data campaigns
This note estimates the ATLAS detector performance in measuring the branching fractions of the very rare decays $B^0_{s} \to \mu^+ \mu^-$ and $B^0 \to \mu^+ \mu^-$ using data collected during the whole LHC Run 2 campaign and during the whole HL-LHC campaign. [...]

Performance of the ATLAS global transverse-momentum triggers at $\sqrt{s}$ = 8 TeV
The global transverse momentum triggers of the ATLAS experiment at the CERN Large Hadron Collider are designed to select collision events with non-interacting particles passing through the detector and events with a large amount of outgoing momentum transverse to the beam axis. [...]

Training and validation of the ATLAS pixel clustering neural networks
The high centre-of-mass energy of the LHC gives rise to dense environments, such as the core of high-pT jets, in which the charge clusters left by ionising particles in the silicon sensors of the pixel detector can merge, compromising the tracking and vertexing efficiency. [...]
