Mini-workshop: Highlights from the Future Circular Collider Design with Path to Construction, and theory aspects of the upcoming precision physics program (ACC+TH)

Monday 13 Oct 2025, 14:25 → 21:05 Europe/Rome

Aula Salvini (Laboratori Nazionali di Frascati)

Accelerator-based particle physics research is entering a momentous phase. 

The update of the European Strategy for Particle Physics is now under way, with the goal of submitting the community recommendation for the next flagship project to the CERN Council next year. Several different projects are currently under evaluation. Moreover, next year the LHC will enter its third long shutdown in order to be upgraded to the HL-LHC.

In this mini-workshop we will focus first on the FCC-ee, and then more broadly on the role of the upcoming precision physics program.

The first presentation will be from Frank Zimmermann and Michael Benedikt from CERN, who will discuss the technical aspects related to the construction of the FCC-ee collider. The second contribution will be from Pier Monni, also from CERN, who will discuss the role (and the challenges) of the precision physics program at the FCC, as well as at the HL-LHC.

If you are coming from outside LNF,  please register so that we can arrange permission for you to enter the campus.

1 Introduction

2 Highlights from the Future Circular Collider Design and Path to Construction

The proposed Future Circular Collider (FCC) integrated programme consists of two stages: An electron–positron collider serving as a highest luminosity Higgs-boson, electroweak and top-quark factory, followed by proton–proton collider with a collision energy around 100 TeV.

In 2021, the CERN Council launched the FCC Feasibility Study. This study covered, inter alia, physics objectives and potential, geology, civil engineering, technical infrastructure, territorial implementation,environmental aspects, R&D needs for the accelerators and detectors, socio-economic benefits, and cost.

The Feasibility Study was completed on 31 March 2025. The subsequent European Strategy Symposium has singled out the FCC as the by-far preferred future collider option for CERN. We present a few study highlights, the status, and the next steps.

4 Gearing up for the precision frontier: theory challenges at HL-LHC and FCC

As the High-Luminosity LHC prepares to deliver an order of magnitude more data, and the planning of future colliders such as the FCC gains momentum, the collider physics programme for the upcoming decades relies critically on the precision of theoretical predictions for scattering observables.

Delivering predictions with the necessary accuracy and flexibility is paramount to enhance the discovery potential of future experiments as well as to stress test the Standard Model and explore its complex structure.
Meeting this challenge requires a collective effort and entails a multitude of obstacles in several areas of theoretical calculations.

In this talk, I will discuss the road ahead and highlight some of the key opportunities and the conceptual and technical challenges that must be tackled in the upcoming years.

Speaker: Pier Francesco Monni (CERN)
