Total cost of ownership and evaluation of Google cloud resources for the ATLAS experiment at the LHC / ATLAS Collaboration
The ATLAS Google Project was established as part of an ongoing evaluation of the use of commercial clouds by the ATLAS Collaboration, in anticipation of the potential future adoption of such resources by WLCG grid sites to fulfil or complement their computing pledges. [...]

Higgs coupling measurements (with emphasis to fermions) at ATLAS and CMS / Trevisani, Nicolo' (KIT, Karlsruhe, EKP) /ATLAS and CMS Collaborations
In the standard model of particle Physics, the Higgs boson is responsible for the electroweak spontaneous symmetry breaking. As a result, particles that interact with the Higgs boson acquire mass [...]

Rare and exotic Higgs decays at ATLAS and CMS / Das, Pallabi (Princeton U., CTP) /ATLAS and CMS Collaborations
After the Higgs boson discovery in 2012, the experiments at the LHC are continuing to study this particle and look for physics beyond the standard model. Some of the Higgs boson properties, such as the mass, has been measured with sub-percent level accuracy. [...]

Top quark mass and cross section at ATLAS and CMS / Faltermann, Nils (KIT, Karlsruhe, EKP) /ATLAS and CMS Collaborations
The top quark is the heaviest elementary particle known to date and therefore an important topic to study in the context of the standard model at the LHC. In this contribution the latest measurements of top quark production cross sections and the top quark mass at the LHC by the ATLAS and CMS Collaborations are presented..

Top quark properties measurements and searches at ATLAS and CMS / Wuchterl, Sebastian (CERN) /ATLAS and CMS Collaborations
Theoretical predictions for processes involving top quarks, such as top quark-antiquark pair production, depend on fundamental standard model (SM) parameters like the top quark mass or potentially receive contributions from beyond-the-SM (BSM) physics. By comparing predictions with measurements performed at the ATLAS and CMS experiments, SM parameters can be determined precisely, or measurements can be used as a powerful probe for BSM physics.
