Rebecca von Kuk, DESY, [HET Theory Seminar], Mass effects in the Higgs q_T spectrum

Thursday 10 Oct 2024, 11:00 → 12:00 US/Eastern

I will discuss 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. I consider the various hierarchies between $m_b$ and $q_T$ and $m_H$, leading to different factorization setups.
