摘要：

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