A lattice determination of moments of unpolarised nucleon structure functions using improved Wilson fermions
M. Göckeler, R. Horsley, D. Pleiter +2
Within the framework of quenched lattice QCD and using O(a) improved Wilson fermions and non-perturbative renormalisation, a high statistics computation of low moments of the unpol…
Target mass corrections for virtual Compton scattering at twist-2 and generalized, non-forward Wandzura-Wilczek and Callan-Gross relations
B. Geyer, D. Robaschik, J. Eilers
The off-cone Compton operator of twist-2 is Fourier transformed using a general procedure which is applicable, in principle, to any QCD tensor operator of definite (geometric) twis…
The polarization tensor of neutral gluons in external fields at high temperature
V. V. Skalozub, A. V. Strelchenko
The one-loop polarization operator of neutral gluons in the background constant Abelian isotopic, , and hypercharge, , chromomagnetic fields combined with elect…
H/A Higgs Mixing in CP-Noninvariant Supersymmetric Theories
S. Y. Choi, J. Kalinowski, Y. Liao +1
For large masses, the two heavy neutral Higgs bosons are nearly degenerate in many 2--Higgs doublet models, and particularly in supersymmetric models. In such a scenario the mixing…
The twist-2 Compton operator and its hidden Wandzura-Wilczek and Callan-Gross relations
B. Geyer, D. Robaschik
Power corrections for virtual Compton scattering at leading twist are etermined at operator level. From the complete off-cone representation of the twist-2 Compton operator integra…
