Next-to-leading order unitarity fits in Two-Higgs-Doublet models with soft ${\mathbb{Z}}_2$ breaking

Vincenzo Cacchio, Debtosh Chowdhury, Otto Eberhardt +1

We fit the next-to-leading order unitarity conditions to the Two-Higgs-Doublet model with a softly broken ${\mathbb{Z}}_2$ symmetry. In doing so, we alleviate the existing uncertaint…
