Large-order Behaviour due to Ultraviolet Renormalons in QCD
M. Beneke, V. M. Braun, N. Kivel
Ultraviolet renormalons, contrary to their infrared counterparts, lead to a universal contribution to the large-order behaviour of perturbative expansions in QCD. In this letter, w…

Heavy Quark Effective Theory beyond Perturbation Theory: Renormalons, the Pole Mass and the Residual Mass Term
M. Beneke, V. M. Braun
We study the asymptotic behaviour of the perturbative series in the heavy quark effective theory (HQET) using the expansion. We find that this theory suffers from an {\it u…
