MISSING ENERGY SIGNALS FROM b-FLAVORED HADRONS AT FCCee

CERN summer student project:

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
including dark sector particles (axion-like particles, dark photons) in the final state, as well as
deeply understand the backgrounds for this measurements.
