Abstract: We analyze critical and massive SO(5) superspin regimes for correlated electrons on a two-leg ladder. We identify fundamental low energy excitations, which carry the quantum numbers of a free electron and can be probed in (inverse) photoemission experiments. These excitations do not obey the usual Pauli principle but are governed by specific forms of the so-called non-Abelian exclusion statistics.
