The pion form factor at timelike momentum transfers in a dispersion approach
D. Melikhov, O. Nachtmann, T. Paulus
We consider a model with , , and gauge-invariant couplings and obtain the pion form factor at timelike momentum transfers by resummation of pion and kaon loops…
Some Remarks on the Pomeron and the Odderon in Theory and Experiment
P. V. Landshoff, O. Nachtmann
On March 19-21, 1998, a workshop devoted to questions of the pomeron and the odderon in high energy scattering was held in Heidelberg. This note gives a personal account of some of…
Parity Violating Energy Shifts and Berry Phases in Atoms, I
D. Bruss, T. Gasenzer, O. Nachtmann
We present a study of parity (P) violating contributions to the eigenenergies of stationary systems containing atoms in spatially inhomogeneous external electric fields. In this co…
Some tests for the helicity structure of the pomeron in collisions
T. Arens, M. Diehl, O. Nachtmann +1
We discuss the reaction in the one-photon exchange approximation, where it is in essence the reaction . A large rapidity gap is req…
Some Remarks on the Search for CP Violation in Z-Decays
W. Bernreuther, O. Nachtmann
We discuss some issues arising in the search for CP violation in the decays Z -> tau+ tau- and Z -> b \bar b X. The form-factor and the effective Lagrangian approach to parametrize…
Optimal observables for measuring three-gauge-boson couplings in
M. Diehl, O. Nachtmann
Observables with optimised sensitivity to the and -couplings in are investigated. They allow for separate studies of CP violation and of absorptive…
