    The Future Circular Collider as a Higgs/top/EW Factory: status and plans for FCC-ee
    Abstract: The 2020 update to the European Strategy for Particle Physics laid out several key priorities for the future of collider physics beyond the Large Hadron Collider (LHC). It identified an electron-positron Higgs factory as the next high-priority experiment and encouraged CERN and its international partners to investigate the technical and financial feasibility of a 100 TeV hadron collider. The integrated Future Circular Collider (FCC) project aims to combine these goals, and would involve a ~90km tunnel being used first for e+e- collisions (FCC-ee) and then for 100 TeV proton-proton collisions (FCC-hh) with additional opportunities for electron proton (FCC-eh) and heavy ion collisions. This seminar will discuss the physics opportunities of FCC-ee, and the status of the FCC feasibility study which is ongoing and has just undergone its mid-term review ahead of completion in 2025. I will also discuss the roadmap ahead which could enable FCC-ee to begin operation in the late 2040s.

    Quantum Sensing for (low and high energy) particle physics
    Abstract:
    The seminar will provide a glimpse of some elements of the rapidly evolving field of quantum sensing, specifically focusing on particle physics. Specific approaches involving quantum systems, such as low-dimensional systems or manipulations of ensembles of quantum systems, hold great promise for improving high-energy particle physics detectors, particularly in areas like calorimetry, tracking, and timing. The use of quantum sensors for high-precision measurements, as well as the development of new quantum sensors based on superconducting circuits, ion and particle traps, crystals, and nanomaterials, are equally relevant for low energy particle physics and for fundamental physics.However, significant advances and improvements in existing or future quantum technologies will be necessary to address such topics related to the dark universe, the detection of relic neutrinos, precision tests of symmetries and of the standard model and probing general foundational issues in physics. The seminar will thus also feature discussions of the Quantum Sensing Initiatives at CERN and the ECFA R&D Roadmap on Quantum Sensing and Advanced Technologies and will discuss options for future collaborations in the context of the imminent implementation of this roadmap.

    FCC project and ALLEGRO detector concept
    Abstract:
    The Future Circular Collider (FCC) is CERN’s next flagship project which fulfills the physics goals of the 2020 update of the European strategy for particle physics set by the European Committee for Future Accelerators. The proposed accelerator would be placed in a 91 km long tunnel to be bored down to 560 m deep under the Geneva region, with the first phase being an electron-positron collider (FCC-ee), followed by an update to a hadron machine (FCC-hh) with proton-proton collision energies of up to 100 TeV. ALLEGRO is a proposed general-purpose experiment for FCC-ee, with a high-granularity noble-liquid electromagnetic calorimeter as a central feature. In this seminar I will give an overview to the status of the FCC project and introduce the ALLEGRO detector concept, with focus on the progress in the development of the next-generation noble-liquid calorimetry technology.
