Description
The FCC-ee program uniquely combines ultra–clean experimental conditions with precise center-of-mass energy calibration—from the Z pole through the top-quark pair threshold—and extraordinarily large event samples of Z and WW bosons. This combination unlocks both direct and indirect probes of physics beyond the standard model through:
-
High-precision electroweak measurements in neutral and charged currents, yielding unprecedented determinations of observables such as the effective weak mixing angle, W- and Z-boson masses, and the top-quark mass.
-
Direct extractions of fundamental couplings, including the strong coupling constant (αₛ) and the fine-structure constant (α), to levels of precision never before achieved.
To fully exploit the statistical precision, a concerted effort is underway to enhance detector performance, refine analysis strategies, and advance
theoretical calculations—thereby driving systematic uncertainties down to meet the tiny statistical uncertainties anticipated.
