  FCC-ee, the lepton version of the Future Circular Collider (FCC), is a 100 Km
future machine under study to be built at CERN. It acquires two experiments
with a highest beam energy of 182.5 GeV. FCC-ee aims to operate at four
different energies, with different luminosities to fulfil physics requirements.
Beam-beam effects at such a high energy/luminosity machine are very challenging
and require a deep understanding, especially in the presence of x-y coupling
sources. Beam-beam effects include the beamstrahlung process, which limits the
beam lifetime at high energies, as well as dynamic effects at the Interaction
point (IP) which include changes in the beta functions and emittances. In this
report, we will define the beam-beam effects and their behaviours in the FCC-ee
highest energy lattice after introducing x-y coupling in the ring.
