Brainstorming over real-time analysis for the Future Circular Collider (FCC)

Summary of the proposed collaboration

The goal of particle physics is to study the existence and interactions of particles, which are the constituents of what is usually referred to as matter or radiation. The theory that describes the particles and their interactions, the Standard Model (SM), has been very successfully confirmed by experiments, such the most recent ATLAS and CMS at the Large Hadron Collider (LHC). Despite its great success in describing nature, the SM leaves many questions unanswered; Physics beyond the SM (BSM) is required to answer these questions. The Future Circular Collider (FCC) project aims at developing conceptual designs with an energy and a luminosity significantly above what the LHC does, significantly extending the possibility to discover BSM physics.

The FCC study puts an emphasis on electron-positron high-intensity and proton-proton high energy frontier machines. A 100 TeV hadron collider in a 100 km long tunnel defines the overall infrastructure for the FCC study. The collision rates at the FCC will be of unprecedented amounts. It will be impossible to store and analyse all data from these produced events: A “trigger system”, performing real-time analysis, will preferably select the potentially interesting interactions, such as those that will contain Higgs particles or signatures of BSM physics.  Typically, the trigger systems is based on fast electronics and highly performant software deciding on a real-time fashion which events to select.

Both the PIs of this proposal have played leading roles in the trigger systems in the ATLAS and CMS experiments, for more than ten years. They propose to brainstorm over the trigger system for the FCC project, building on their expertise and experience from the previous experiments.
