Prof. Stanislaw Jadach (IFJ PAN): Invisible decays of Z boson: recent improvements and future prospects

Europe/Warsaw
Description

Abstract:

Recent experimental and theoretical improvements in the analysis of old LEP data are showing better agreement of the Z boson decays into final states invisible in the detector with the Standard Model predictions. 

The 20-years-old 2σ tension of data with the Standard Model is gone. Prospects of much high precision measurements of the Z invisible width at the FCC-ee collider using several methods will be also covered.
