Bounds on Ratios of DIS Structure Functions from the Color Dipole Picture
Carlo Ewerz, Otto Nachtmann
We derive bounds on ratios of deep inelastic nucleon structure functions from the color dipole picture of high energy photon-hadron scattering. We find an upper bound on the ratio…
Determining the global minimum of Higgs potentials via Groebner bases - applied to the NMSSM
M. Maniatis, A. von Manteuffel, O. Nachtmann
Determining the global minimum of Higgs potentials with several Higgs fields like the next-to-minimal supersymmetric extension of the Standard Model (NMSSM) is a non-trivial task a…
Chiral Symmetry and Diffractive Neutral Pion Photo- and Electroproduction
Carlo Ewerz, Otto Nachtmann
We show that diffractive production of a single neutral pion in photon-induced reactions at high energy is dynamically suppressed due to the approximate chiral symmetry of QCD. The…
Stability and Symmetry Breaking in the General Two-Higgs-Doublet Model
M. Maniatis, A. von Manteuffel, O. Nachtmann +1
A method is presented for the analysis of the scalar potential in the general Two-Higgs-Doublet Model. This allows us to give the conditions for the stability of the potential and…
Towards a Nonperturbative Foundation of the Dipole Picture: II. High Energy Limit
Carlo Ewerz, Otto Nachtmann
This is the second of two papers in which we study real and virtual photon-proton scattering in a nonperturbative framework. In the first paper we have identified the leading contr…
