It is easy to check that both algebraic equation Det(^p - m) = 0 and Det(^p + m) = 0 for 4-spinors u- and v- have solutions with (see paper) The same is true for higherspin equations. Meanwhile, every book considers the p0 = Ep only for both u- and v- spinors of the (see paper) representation, thus applying the Dirac-Feynman-Stueckelberg procedure for elimination of negative-energy solutions. Recent works of Ziino (and, independently, of several others) show that the Fock space can be doubled. We re-consider this possibility on the quantum field level for both s = 1/2 and higher spins particles.
