In this letter, we extend the known results for the QCD potential between a static quark and its antiquark by computing the two-loop corrections to the colour-octet state. PACS numbers: 12.38.Bx, 12.38.-t The QCD potential between a static quark and its antiquark has for a long time been used as a probe of the fundamental properties of the strong interactions such as asymptotic freedom and conf...

We present a novel online learning approach for statistical machine translation tailored to the computer assisted translation scenario. With the introduction of a simple online feature, we are able to adapt the translation model on the fly to the corrections made by the translators. Additionally, we do online adaption of the feature weights with a large margin algorithm. Our results show that o...

A recently introduced stochastic model for fluid flow can be made Galilean invariant by introducing a random shift of the computational grid before collisions. This grid shifting procedure accelerates momentum transfer between cells and leads to a collisional contribution to transport coefficients. By resumming the Green-Kubo relations derived in a previous paper, it is shown that this collisio...

Using newly calculated electromagnetic corrections [1], [2], we have made a phase shift analysis of the experimental data on πp elastic scattering up to a pion laboratory kinetic energy of 100 MeV. The effective hadronic interaction was assumed to be isospin invariant. The output consists of six hadronic phase shifts in parametrised form: the s-, p1/2and p3/2-waves for total isospin 3/2 and 1/2...

We examine the quantum corrections to the static energy for Higgs winding configurations in order to ascertain whether such corrections may stabilize solitons in the standard model. We evaluate the effective action for winding configurations in Weinberg-Salam theory without U(1)gauge fields or fermions. For a configuration whose size, a ≪ m−1 where m = max{mW ,mH}, mW is the W-mass, and mH is t...

We examine the quantum corrections to the static energy for Higgs winding configurations. We evaluate the effective action for such configurations in Weinberg-Salam theory without U(1)-gauge fields or fermions. For a configuration whose size is much smaller than the inverse W-mass, quantum contributions to the energy are comparable to the classical energy. Moreover, it is insufficient to consid...
