Five-loop renormalization group calculations in the gϕ4 theory

The β-function and the mass anomalous dimension in the gϕ (4) 4 model are calculated pertubatively through five loops in the MS-scheme, and resummed via a Borel-like technique. The behaviour β resum five loops, independently of the renormalization scheme.
