Two-loop analysis of classically scale-invariant models with extended Higgs sectors
Two-loop analysis of classically scale-invariant models with extended Higgs sectors
A bstract We present the first explicit calculation of leading two-loop corrections to the Higgs trilinear coupling λ hhh in models with classical scale invariance (CSI), using the effective-potential approximation. Furthermore, we also study — for the first time at two loops — the relation that appears between the masses …
