  In composite Higgs models, new composite pseudoscalars can interact with the
Higgs and with electroweak gauge bosons via anomalous interactions, which stem
from the topological structure of the underlying theory. A future 100 TeV pp
collider (FCC-pp) will be able to test these anomalous interactions and thus
shed light on the strong dynamics which generates the Higgs and other composite
resonances. We will discuss the topological interactions of a minimal composite
Higgs model with fermionic ultraviolet completion, based on the coset
SU(4)/Sp(4). We will indicate the strategy to test these interactions at the
FCC-pp and the expected reach.
