Description
We present results of the six loop renormalization group calculations of the critical exponents in $O(n)$-symmetric $\phi^4$ theory in the framework of $\epsilon$-expansion (minimal subtraction scheme). Technical details of this calculations are discussed. Obtained results are compared with experimental data and with results of other theoretical approaches like $1/n$ expansion, renormalization group in fixed space dimension, high temperature expansion and Monte-Carlo simulations.
