Luminosity determination at COSY-11 using the pd elastic scattering — •S. Steltenkamp — Institut für Kernphysik, Universität Münster, Germany
Measurements on the near-threshold η and η′ meson production in the reaction channel pd→ 3He X have been performed at the internal beam experiment COSY-11 [1,2]. To extract total and differential cross sections, the proton-deuteron elastic scattering has been measured simultaneously as reference reaction for normalization purposes. Close to the η and η′ meson production thresholds (pthr.,η = 1.570 GeV/c, pthr.,η′ = 2.434 GeV/c) the COSY-11 facility allows for an identification and momentum reconstruction of elastically scattered protons using a set of two drift chambers and a scintillation wall. Additionally, a granulated silicon pad detector enables to detect the corresponding deuterons in coincidence.
The experimental method will be discussed and recent results will
be presented.
