Diphoton decay of the higgs from the Epstein–Glaser viewpoint

Duch, P. ; Dütsch, M. ; Gracia-Bondía, J.M. (Universidad de Zaragoza)

Resumen: We revisit a nearly 10-year old controversy on the diphoton decay of the Higgs particle. To a large extent, the controversy turned around the respective merits of the regularization techniques employed. The novel aspect of our approach is that no regularization techniques are brought to bear: we work within the Bogoliubov–Epstein–Glaser scheme of renormalization by extension of distributions. Solving the problem actually required an expansion of this method’s toolkit, furnished in the paper.
