  Mass effects in the Higgs qT spectrum¶ 1h 30m
  
  I will discuss quark mass effects in the Higgs $q_{T}$ spectrum which are important to measure the Yukawa coupling from the initial state. I will begin with a new prediction for quark initiated Higgs production at N3LL' matched to an approximate N3LO. The main part of the talk will focus on 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 $H \to γ γ$ decay or the $g g \to H$ 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. I consider the various hierarchies between $m_{b}$ and $q_{T}$ and $m_{H}$ , leading to different factorization setups.
