Abstract
We have calculated the five-loop RG expansions of the -component A model of critical dynamics in dimensions within the Minimal Subtraction scheme. This is made possible by using the advanced diagram reduction method and the Sector Decomposition technique adapted to the problems of critical dynamics. The expansions for the critical dynamic exponent for an arbitrary value of the order parameter dimension are derived. Based on these series, the numerical estimates of for different universality classes are extracted and compared with the results obtained within different theoretical and experimental methods.
