It is shown, by using Grassmann space to describe the internal degrees
of freedom of fermions and bosons, that the Weyl-like equation exists
not only for massless fermions but also for massless vector bosons. T
he corresponding states have well defined helicity and handedness. It
is also shown that spinors and vector bosons interact only if both are
of the same handedness.
