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. Seamless integration of Google cloud resources into the worldwide ATLAS distributed computing infrastructure was achieved at large scale and for an extended period of time, and hence cloud resources are shown to be an effective mechanism to provide additional, flexible computing capacity to ATLAS.

Results are presented on searches for additional Higgs bosons using the CMS Run 2 data. The search covers both low mass (below 125 GeV), in the diphoton and ditau channel, and higher masses in the decays into b jets and a top pair. [...]

This talk will highlight the latest results from CMS, ATLAS, and LHCb on precision electroweak measurements, including the W boson mass, sin2thetaW, and the g-2 from tau leptons, as well as recent determinations of the strong coupling constant, alphaS, in quantum chromodynamics (QCD)..

To verify the readiness of the data distribution infrastructure for the HL-LHC, which is planned to start in 2029, WLCG is organizing a series of data challenges with increasing throughput and complexity. This presentation addresses the contribution of CMS to Data Challenge 2024, which aims to reach 25% of the expected network throughput of the HL-LHC. [...]

In composite Higgs models the scalar particles in the Higgs sector are not elementary particles, but of composite nature, arising as pseudo Nambu-Goldstone bosons from new broken symmetries. In a composite 2-Higgs-Doublet Model (2HDM) thus a 2HDM-like structure is generated, but with couplings already predetermined by the composite nature of the model. [...]
