It is easy to check that both algebraic equation $Det (hat p  m) =0$ and $Det (hat p + m) =0$ for $u$ and $v$ 4spinors have solutions with $p_0= pm E_p =pm sqrt{{bf p}^2 +m^2}$. The same is true for higherspin equations. Meanwhile, every book considers
the equality $p_0=E_p$ for both $u$ and $v$ spinors of the $(1/2,0)oplus (0,1/2))$ representation only, thus applying the DiracFeynmanStueckelberg procedure for elimination of the negativeenergy solutions. The recent Ziino works (and, independently,
the articles of several others) show that the Fock space can be doubled. We reconsider this possibility on the quantum field level for both $s=1/2$ and higher spin particles.
