Higher-twist contributions to F_L and F_2 from instantons
B. Dressler, M. Maul, C. Weiss
We study the twist-4 contribution to the unpolarized nucleon structure functions, F_L and F_2, in an approach where the vacuum structure of QCD is described by a dilute medium of i…
Do Instantons of the CP(N-1) Model Melt?
M. Maul, D. Diakonov
In the two-dimensional CP(N-1) model one can parametrize exact many-instanton solutions via N `constituents' (called `zindons'). This parameterization allows, in principle, a compl…
Twist-4 contribution to unpolarized structure functions F_L and F_2 from instantons
B. Dressler, M. Maul, C. Weiss
We compute in the instanton vacuum the nucleon matrix elements of the twist-4 QCD operators describing power corrections to the second moments of the unpolarized structure function…
Stark quenching for the level in beryllium-like ions and parity-violating effects
M. Maul, A. Schafer, P. Indelicato
In this paper we present some concepts in heavy ion atomic physics for the extraction of parity violating effects. We investigate the effects of the so-called Stark-quenching, i.e.…
