Understanding perturbative results for decays of τleptons into hadrons
S. Groote, J. G. Körner, A. A. Pivovarov
We review some results obtained by us and others concerning the structure of higher order perturbation series in perturbative QCD and their resummation using the renormalization gr…
Renormalization group approach to chaotic strings
Stefan Groote, Hardi Veermäe, Christian Beck
Coupled map lattices of weakly coupled Chebychev maps, so-called chaotic strings, may have a profound physical meaning in terms of dynamical models of vacuum fluctuations in stocha…
O(α_s) corrections to the decays of polarized W^+- and Z bosons into massive quark pairs
S. Groote, J. G. Körner, P. Tuvike
We present O(α_s) results on the decays of polarized W^+- and Z bosons into massive quark pairs. The NLO QCD corrections to the polarized decay functions are given up to the second…
A numerical test of differential equations for one- and two-loop sunrise diagrams using configuration space techniques
S. Groote, J. G. Körner, A. A. Pivovarov
We use configuration space methods to write down one-dimensional integral representations for one- and two-loop sunrise diagrams (also called Bessel moments) which we use to numeri…
