Initial guidelines for a social cost-benefit analysis of the FCC programme / Bastianin, Andrea (Università degli Studi di Milano - Bicocca, Italy) ; Florio, Massimo (Università degli Studi di Milano, Italy)
A fully-fledged Social Cost Benefit Analysis (CBA) of one of the Future Circular Collider Conceptual Design Report’s (FCC CDR) scenarios would require making assumptions on several key variables relating both with the costs and benefits generated by future research infrastructures (RI) over a very long time-span. Presenting results of such a comprehensive analysis is well beyond the scope of this report. [...]

Higgs boson cross sections for the high-energy and high-luminosity LHC: cross-section predictions and theoretical uncertainty projections / Calderon Tazon, Alicia (Universidad de Cantabria and CSIC (ES)) ; Caola, Fabrizio (University of Durham (GB)) ; Campbell, John (Fermilab (US)) ; Francavilla, Paolo (Universita & INFN Pisa (IT)) ; Marchiori, Giovanni (Centre National de la Recherche Scientifique (FR)) ; Becker, Kathrin (Albert Ludwigs Universitaet Freiburg (DE)) ; Bertella, Claudia (Chinese Academy of Sciences (CN)) ; Bonvini, Marco (Sapienza Universita e INFN, Roma I (IT)) ; Chen, Xuan (Zuerich University (CH)) ; Frederix, Rikkert (Technische Universität Muenchen (DE)) et al.
This note summarizes the state-of-the-art predictions for the cross sections expected for Higgs boson production in the 27 TeV proton-proton collisions of a high-energy LHC, including a full theoretical uncertainty analysis. It also provides projections for the progress that may be expected on the timescale of the high-luminosity LHC and an assessment of the main limiting factors to further reduction of the remaining theoretical uncertainties..

Manufacturing process of superconducting magnets: Analysis of manufacturing chain technologies for market-oriented industries / Kretzschmar, Linn (WU Wien) ; Mehner, Barbara ; Hartig, Heinrich (WU Wien) ; Hausberger, Matthias (WU Wien) ; Ldermüller, Frederik (WU Wien) ; Mayrhofer, Ferdinand (WU Wien) ; Schreiber, Daniel (WU Wien) ; Gutleber, Johannes (CERN)
The aim of this investigation was to identify the industrial impact potentials of the key processes needed for the manufacturing of novel high-field superconducting magnets and to find innovative additional applications for these technologies outside the particle-accelerator domain. Suppliers and manufacturing partners of CERN would benefit if the know-how could be used for other markets and to improve their internal efficiency and competitivity on the world-market. [...]
