The European Strategy for Particle Physics ESPP has recommended a financial and technical feasibility of the FCC colliders and their infrastructure to be carried out for its next upgrade around 2025/6. The integral FCC program combines in the same 100km infrastructure a high luminosity Higgs and Electroweak factory e+e- collider, FCC-ee, followed by a 100 TeV hadron collider. With its high luminosity, its clean experimental conditions, and a range of energies that cover the four heaviest particles known today, FCC-ee offers a wealth of physics possibilities, with high potential for discoveries. It is an essential and complementary step towards the 100 TeV hadron collider, and the whole combined program is uniquely rich and powerful. This vision is the backbone of the 2020 ESPP.
The main challenges of the study are now to design the detector systems that can, demonstrably, fully exploit its potential, while being technically feasible and affordable on the project time scale (start of operations around 2040). With 5.1012 Z produced, the TeraZ run offers b,c,  and QCD physics opportunities, as well as ppm precision challenges on electroweak precision observables and unique searches for extremely rare processes. This breath of opportunities requires very varied and quite specific detector requirements, compared with the higher energy program on Higgs and top physics which is more comparable to the linear collider detector optimization. This variety is clearly in favour of a collider design which foresees four experimental interaction regions. The high precision and varied program is also a considerable challenge for precision calculations.
The opportunities will be reviewed and the most striking detector challenges will be highlighted.
