Description
H-COUP is a computational tool for evaluating Higgs-boson decay rates and branching ratios, including one-loop corrections, in various extended Higgs sectors. Such precision calculations are essential for interpreting future measurements at Higgs factories, such as the ILC, FCC-ee, and CEPC, and for probing the underlying structure of the Higgs sector.
In this talk, we present the main features of H-COUP and discuss ongoing developments toward Version 4.
