Higgs self-coupling beta-function in the Standard Model at three loops    [PDF]

A. V. Bednyakov, A. F. Pikelner, V. N. Velizhanin

We present the results for three-loop beta-function for the Higgs self-coupling calculated within the unbroken phase of the Standard Model. We also provide the expression for three-loop beta-function of the Higgs mass parameter, which is obtained as a by-product of our main calculation. Our results coincide with that of recent paper arXiv:1303.2890. In addition, the expression for the Higgs field anomalous dimension is given.
