Improved radiative corrections and proton charge form factor from the Rosenbluth separation technique

Florian Weissbach, Kai Hencken, Dirk Trautmann +1

We investigate whether the apparent discrepancy between proton electric form factor from measurements using the Rosenbluth separation technique and polarization transfer method is…

Improved radiative corrections for (e,e'p) experiments - A novel approach to multi-photon bremsstrahlung

Florian Weissbach, Kai Hencken, Daniela Kiselev +1

Radiative processes lead to important corrections to (e,e'p) experiments. While radiative corrections can be calculated exactly in QED and to a good accuracy also including hadroni…

Boundary-Layer Theory, Strong-Coupling Series, and Large-Order Behavior

Carl M. Bender, Axel Pelster, Florian Weissbach

The introduction of a lattice converts a singular boundary-layer problem in the continuum into a regular perturbation problem. However, the continuum limit of the discrete problem…

High-Order Variational Perturbation Theory for the Free Energy

Florian Weissbach, Axel Pelster, Bodo Hamprecht

In this paper we introduce a generalization to the algebraic Bender-Wu recursion relation for the eigenvalues and the eigenfunctions of the anharmonic oscillator. We extend this we…

Variational Perturbation Theory for the Ground-State Wave Function

Axel Pelster, Florian Weissbach

We evaluate perturbatively the density matrix in the low-temperature limit and thus the ground-state wave function of the anharmonic oscillator up to second order in the coupling c…
