Higgs production and decay: analytic results at next-to-leading order QCD
Higgs production and decay: analytic results at next-to-leading order QCD
The virtual two-loop corrections for Higgs production in gluon fusion are calculated analytically in QCD for arbitrary Higgs and quark masses. Both scalar and pseudo-scalar Higgs bosons are considered. The results are obtained by expanding the known one-dimensional integral representation in terms of m_H/m_q, and matching it with a suitably …
