Relativistic SkyrmionsIs there a relativistic wave equation with this spectrum?Might help us to think of small mass fermions as solitons aswell.For example, there might be a technicolor model in which theanalogues of mesons are Higgs bosons and the analogues ofbaryons are the leptons.The tricky part is to extend the rotations to Lorentztransformations.The obvious generalization ψ + m 2 + K∆ gψ = 0hastoomuch symmetrySpin and orbital angular momentum must not be separatelyconserved in a relativistic theory.S.
