Higher-order QCD corrections to H → b b ¯ $$ \overline{b} $$ from rational approximants

Abstract We use rational approximants to study missing higher orders in the massless scalar-current quark correlator. We predict the yet unknown six-loop coefficient of its imaginary part, related to Γ(H → b b ¯ $$ \overline{b} $$ ), to be c 5 = −6900 ± 1400. With this result, the perturbative serie...
