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…
On the twist-3 contribution to h_L in the instanton vacuum
B. Dressler, M. V. Polyakov
We show that the instanton model of the QCD vacuum indicates the parametric smallness of the twist-3 contributions to the polarized structure function h_L. This smallness is relate…
Polarized antiquark flavor asymmetry in Drell-Yan pair production
B. Dressler, K. Goeke, M. V. Polyakov +3
We investigate the role of the flavor asymmetry of the nucleon's polarized antiquark distributions in Drell-Yan lepton pair production in polarized nucleon-nucleon collisions at HE…
Flavor asymmetry of polarized antiquark distributions and semi-inclusive DIS
B. Dressler, K. Goeke, M. V. Polyakov +1
The -expansion of QCD suggests large flavor asymmetries of the polarized antiquark distributions in the nucleon. This is confirmed by model calculations in the large- l…
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…
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…
