Three-loop Euler-Heisenberg Lagrangian in 1+1 QED, part 1: single fermion-loop part
Idrish Huet, Michel Rausch de Traubenberg, Christian Schubert
We study the three-loop Euler-Heisenberg Lagrangian in spinor quantum electrodynamics in 1+1 dimensions. In this first part we calculate the one-fermion-loop contribution, applying…
QCD gluon vertices from the string-inspired formalism
Naser Ahmadiniaz, Christian Schubert
The Bern-Kosower formalism, developed around 1990 as a novel way of obtaining QCD amplitudes as the limit of infinite string tension of the corresponding string amplitudes, was ori…
On the low-energy limit of the QED N-photon amplitudes: part 2
James P. Edwards, Adolfo Huet, Christian Schubert
In recent work, Gies and Karbstein have discovered that the two-loop Euler-Heisenberg Lagrangians for scalar and spinor QED have non-vanishing reducible contributions in addition t…
Multiloop Euler-Heisenberg Lagrangians, Schwinger pair creation, and the QED N - photon amplitudes
Idrish Huet, Michel Rausch de Traubenberg, Christian Schubert
An update is given on our long-term effort to perform a three-loop check on the Affleck-Alvarez-Manton/Lebedev-Ritus exponentiation conjecture for the imaginary part of the Euler-H…
