On the Energy Dependence of the Dipole-Proton Cross Section in Deep Inelastic Scattering
Carlo Ewerz, Andreas von Manteuffel, Otto Nachtmann
We study the dipole picture of high-energy virtual-photon-proton scattering. It is shown that different choices for the energy variable in the dipole cross section used in the lite…

A new type of CP symmetry, family replication and fermion mass hierarchies
M. Maniatis, A. von Manteuffel, O. Nachtmann
We study a two-Higgs-doublet model with four generalised CP symmetries in the scalar sector. Electroweak symmetry breaking leads automatically to spontaneous breaking of two of the…
On the Limitations of the Color Dipole Picture
Carlo Ewerz, Andreas von Manteuffel, Otto Nachtmann
We discuss two aspects of the color dipole picture of high energy photon-proton scattering. First we present bounds on various ratios of deep inelastic structure functions resultin…
On the Range of Validity of the Dipole Picture
Carlo Ewerz, Andreas von Manteuffel, Otto Nachtmann
We derive correlated bounds on ratios of deep inelastic structure functions from the dipole picture of photon-hadron scattering at high energies. In particular we consider ratios o…
Diffractive Neutral Pion Production, Chiral Symmetry and the Odderon
Carlo Ewerz, Otto Nachtmann
We discuss the diffractive photo- and electroproduction of a single neutral pion at high energies where it can occur due to odderon exchange. We show that this process is dynamical…
