Abstract: Strongly coupled 5d $\mathcal{N}=1$ gauge theories have a Higgs branch of their moduli space of vacua, identified by 1/2-BPS operators and their algebraic relations. For $SU(N_c)_k$ theories, we map the moduli space across different phases and we establish how the Chern-Simons level $k$ deforms the chiral ring relations among mesons, baryons, and instantons, while determining specific patterns of symmetry enhancement. For $SO(N_c)$ theories, we construct the corresponding chiral ring constraints at infinite coupling. Finally, we identify the Higgs branch as a classical integrable system, through the expansion of the chiral ring in terms of action variables.
