Description
We investigate finite b-mass effects arising from the bottom-loop in gluon-fusion Higgs production in the Higgs $q_T$ spectrum. In contrast to the cases of the $H \to\gamma\gamma$ decay or the $gg\to H$ form factor investigated previously at amplitude level, in this case the nontrivial b-mass effects are also resolved by real emissions and have to be considered within the context of $q_T$ factorization and resummation.
We consider the various hierarchies between $m_b$ and $q_T$ and $m_H$, leading to different factorization setups.
