On the possibility of primordial torsion detection from magnetic   helicity and energy spectra
  The purpose of this paper is twofold: First lending more support to torsion alternative gravity theories to General Relativity and cosmology and torsion detection by showing how they can simply used in the investigation of helicity and magnetic energy spectra of primordial fields by using a strong value of torsion of $10MeV$ previously computed by the author. dynamo mechanism seeds in the Primordial Universe has been a matter of intense investigation lately. The second purpose is to apply these torsion theories in the special random spins gauge where its time component torsion gauge $T^{0}=0$, which implies that spins of the nucleons are polarised orthogonal to QCD domain walls. A modification of circular polarization at $1Mpc$ scale, give rise to left torsion helicity which using a QCD seed $B_{QCD}\sim{10^{16}G}$ yields MF of $B_{-}\sim{10^{30}Gauss}$ which was the value obtained by Enqvist et al using neutrinos and galactic dynamos at QED scales. The $B_{+}$ mode can be shown to constrain torsion to $T\sim{10^{7}Mev}$ at $1pc$ which can be detected at LHC scales. These constraints at 1Mpc reach only $10^{-10}MeV$
