Revisiting the Higgs-mass calculation in the scale-invariant THDM
Pietro Slavich
We revisit the one-loop calculation of the Higgs-mass spectrum of the scale-invariant THDM, relying on a direct calculation of the relevant Feynman diagrams. We highlight a number…

Two-loop BSM contributions to Higgs pair production in the aligned THDM
Giuseppe Degrassi, Ramona Gröber, Pietro Slavich
We study the impact of the two-loop corrections controlled by the BSM Higgs couplings on the cross section for the production of a pair of SM-like Higgs bosons via gluon fusion in…

On the two-loop BSM corrections to in a triplet extension of the SM
Giuseppe Degrassi, Pietro Slavich
We compute the two-loop BSM contributions to the decay width in the SM extended with a real triplet of . We consider scenarios in which the neutral c…
