b-flavored hadrons decaying into a final state containing missing energy are of key importance to flavor physics, particularly in searches for new physics. In this context, electron-positron colliders running at the Z peak offer key conditions to explore this type of decays due to their clean environment and also because the initial energy is known. Given the high interest on a future TeraZ factory at FCCee, the aim of this project is to explore the type of signals that could be probed with 10^12 Z bosons, specifically very suppressed SM decays and also BSM decays hitting the dark sectors (axion-like particles, dark photons), as well as deeply understand the backgrounds for this measurements..
