Abstract
The critical behaviour of helimagnets and stacked triangular antiferromagnets is analyzed in 4 − ϵ dimensions within the three-loop approximation. Numerical estimates for marginal values of the order parameter dimensionality N obtained by resummation of corresponding ϵ-expansions rule out the possibility of continuous chiral transitions in magnets with Heisenberg or planar spins.
