Bottom and Top loop structure in ggH and ggA

Authors: Diogo Buarque Franzosi and Cen Zhang

Description

This model allows the user to compute (pseudo-)scalar production through loop-induced gluon fusion at LO. Any decay can be specified and interference with tree-level background is included when it applies. It takes into account the full top and bottom loops.

After loading the model with

import model Higgs_Effective_Couplings_FormFact

the user can run, for instance:

p p > h > t t~ (signal scalar)

p p > h1 > t t~ (signal pseudo-scalar)

p p > t t~ HIG=1 / h1 (signal scalar + background and interference)
