Abstract
The wavevector q associated with the helical order varies along the paramagnetic-helical critical line as mod q mod approximately mod p mod beta k, as a Lifshitz point (T=TL, p=0) is approached. Renormalisation group techniques in d=4+1/2m- epsilon ( epsilon >0) dimensions are used to calculate the critical exponent beta k, associated with an m-fold Lifshitz point, to second order in epsilon .Keywords
