One-loop corrections for lambda are computed.
Results are compared with previous calculations by Durand et al.
The study highlights gauge dependence in the amplitude calculations.
Abstract
The amplitude of Higgs-Higgs interaction is calculated in the Standard Model in the framework of the Sirlin's renormalization scheme in the unitary gauge. The one-loop corrections for lambda, the constant of 4-chi interaction are compared with the previous results of L. Durand et al. obtained on using the technique of the equivalence theorem, and in the different gauges.
