2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/49478We review the comparison of the results for the neutral CP-even Higgs-boson masses recently obtained within the Feynman-diagrammatic approach with the previous results based on the renormalization group approach. We show that the results differ by new genuine two-loop contributions present in the Feynman-diagrammatic calculation. The numerical effect of these terms on the result for m_h is briefly discussed.5 pages, 1 figure, to appear in the proceedings of the International Workshop on Linear Colliders, Sitges, April 28 - May 5, 1999High Energy Physics - Phenomenologytext
