Search for ω-mesic states∗ — •Stefan Friedrich — II. Physikalisches Institut, Universität Gießen, Heinrich-Buff-Ring 16, 35392 Gießen
Experiments searching for the existence of ω-mesic states are presented,
using the tagged photon beam at the ELSA accelerator in Bonn.
The combined setup of the Crystal Barrel and MiniTAPS detector systems,
which form a 4π electromagnetic calorimeter, was used for detecting
the possible ω-mesic states via the ω→π∘+γ decay mode.
The recoiling proton of the γ+p→ω+p reaction was identified
with an aerogel Cherenkov detector and the forward angle spectrometer MiniTAPS.
Two experiments on a carbon target have been performed as well a reference measurement on LH2.
The status of the analysis will be presented.
