  The analogy between the Skyrme and Higgs field leads to the conjecture that
all fermions are skyrmions and thus always carry conserved quantum numbers,
which are identified with baryon or lepton quantum numbers. This connection
between spin and quantum numbers, which parallels the connection between spin
and statistics due to the Pauli principle, may explain why supersymmetry has
not been observed. Creation of s-particles at higher than present energies due
to a breakdown of the Skyrme mechanism might imply the violation of the
exclusion principle.
