  In strongly coupled gauge theories that serve as completions of composite
Higgs models, the fermionic bound states formed by fermions (hyperquarks)
transforming in different representations, called chimera baryons, could serve
as top partners, by embedding of the Standard Model appropriately. We report
our results on the spectrum of chimera baryons in the Sp(4) gauge theory with
hyperquarks transforming in fundamental and two-index antisymmetric
representations. For this study, we adopt the quenched approximation. We
investigate the mass hierarchy between the lightest chimera baryons with
different quantum numbers, as a function of the lattice parameters. Inspired by
baryon chiral effective field theory, and the Akaike Information Criterion, we
perform a first extrapolation to the continuum and massless-hyperquark limit.
