Charge Asymmetry Studies in the Process e p → π⁺ π⁻ p at the H1 Detector at HERA — •Arthur Bolz — Physikalisches Institut, Universität Heidelberg, Im Neuenheimer Feld 226, D-69120 Heidelberg, Germany

In a recent publication (arXiv:1409.8483) the possibility of charge asymmetries due to pomeron-odderon and pomeron-photon interference effects in the process γ p → π⁺π⁻ p is discussed. Systematic studies are currently performed to see whether such asymmetries can be measured in data taken by the H1-detector at the HERA electron-proton collider. At H1 a large sample of photo-produced pion pairs triggered by the Fast Track Trigger exists, which can be used to search for such effects. Studies for detector effects that might spoil the sensitivity for the asymmetries discussed in the model are currently performed. First results will be presented.
