Now we consider the primary species of dark matter as the neutralino, which might be a Majorana spinor field and act as its own antimatter.

As such the position spinor x is related to the momentum spinor p by a "motion," similar to x = x0 + vt.

A twistor is a pair of spinors well what's a spinor?

As spinor is a variable which has algebraic properties identical to that of angular momentum or spin.

I have ideas that the Dbranes have spinor structure similar to electrons which constrain some of that structure in ways.

But then you take the commutator of two covariant derivatives acting on this spinor field and get a relation involving the Riemann tensor.

Being that the supersymmetry variation of the gravitino is the covariant derivative of the local spinor parameterizing the supersymmetry transformation, this would seem to always imply that the condition for supersymmetry is that there must exist a covariantly constant spinor field.

For gravity I turn to the Weyl tensor C_ {abcd}, which is the traceless component of Riemann curvature tensor for spacetime, and in spinor form this may be written as

The spinor solutions of the Dirac equation have positive and negative solutions, just as the quadratic equation often has positive and negative solutions.

The mass which couples the two equations is due to the Higgs field with the Yukawa Lagrangian L = barpsi H psi which in spinor components is
