We show that in a two-dimensional σ model whose
fields only depend on one target space coordinate, the O(d,d)
invariance of the conformal invariance conditions observed at one
loop is preserved at two...
The aim of this thesis was (i) to develop
analytical methodologies and a workflow to identify the
ocean-continent transition (OCT) and to locate the continent-ocean
crustal and lithosphere boundaries ...
Revascularization of the ischemic myocardium is one
of the major concerns in the field of experimental surgery. The
increasing disability and death from obliterative disease of the
coronary arteries, ...
We compute the one loop corrections to the pole
mass of the gluon in the MSbar scheme in the Landau gauge in both
the Curci-Ferrari model and the local composite operator formalism
with Nf flavours of...
We use the Gribov-Zwanziger Lagrangian in QCD to
evaluate the one loop correction to the gluon propagator as a
function of the Gribov volume and verify that the propagator
vanishes in the infrared lim...
We compute the one loop anomalous dimension of the
gauge invariant dimension two operator min_U (A^U_mu)^2, where U is
an element of the gauge group, by exploiting Zwanziger's expansion
of the operato...
Göckeler, M., Horsley, R., Perlt, H., Rakow, P.E.L., Schäfer, A., Schierholz, G., Schiller, A.,
We calculate the non-forward quark matrix elements
for operators with two covariant derivatives in one-loop lattice
perturbation theory using Wilson fermions. These matrix elements
are needed in the r...
We construct a superpotential for the general N=1/2
supersymmetric gauge theory coupled to chiral matter in the
fundamental and adjoint representations, and investigate the
one-loop renormalisability ...
