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…

Flavor asymmetry of polarized and unpolarized sea quark distributions in the large-N_c limit
B. Dressler, K. Goeke, P. V. Pobylitsa +3
We summarize recent attempts to calculate the flavor asymmetry of the nucleon's sea quark distributions in the large- limit, where the nucleon can be described as a soliton of…
