Convergence of interference term at next-to-next-to-leading order in Higgs boson to b bbar decay
Higgs boson decay to bottom, anti-bottom quarks is the major decay channel due to the fact that these quarks have a relatively high mass and the Higgs coupling to a particle is proportional to its mass. This process is difficult to detect experimentally because of the jets produced by the quarks. In computations of this decay at next-to-next-to-leading order (NNLO), there is a specific term which
