A simple generalization of the low-energy theorem for the effective Higgs-gluon-gluon coupling for the case of simultaneous decoupling of several heavy quarks

Konstantin G. Chetyrkin

We extend in an extremely simple and straightforward way the well-known low-energy theorem for an effective Higgs-like scalar-gluon-gluon coupling [1] (as well as a similar one for…

The and form factors to NNLO accuracy in perturbative QCD

V. M. Braun, K. G. Chetyrkin, A. N. Manashov

We use conformal symmetry to calculate the NNLO anomalous dimension matrix (three loops) for flavor-singlet axial-vector QCD operators for spin from a set of gauge-invari…

The method of global R* and its applications

K. G. Chetyrkin, G. Falcioni, F. Herzog +1

The global R* operation is a powerful method for computing renormalisation group functions. This technique, based on the principle of infrared rearrangement, allows to express all…

Five-Loop Running of the QCD coupling constant

P. A. Baikov, K. G. Chetyrkin, J. H. Kühn

We analytically compute the five-loop term in the beta function which governs the running of --- the quark-gluon coupling constant in QCD. The new term leads to a reduction o…

Massless propagators: applications in QCD and QED

P. A. Baikov, K. G. Chetyrkin, J. H. Kühn

We report on two recent results based on the evaluation of five-loop massless propagators in QCD and QED: (i) corrections of order to the absorptive part of the polarizatio…

Top Quark Mediated Higgs Decay into Hadrons to Order alpha(s)**5

P. A. Baikov, K. G. Chetyrkin

We present in analytic form the O(alpha_s^5) correction to the H->gg partial width of the standard-model Higgs boson with intermediate mass M_H<2M_t. Its knowledge is useful becaus…
