Search for ω-mesic nuclei∗ — •Karoly Makonyi and Stefan Friedrich — II. Physikalisches Institut, Heinrich-Buff-Ring 16, 35392 Giessen
The existence and properties of ω-mesic nuclei are being
studied with the tagged photon beam of 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
and the conversion (ω+N→ N*→ π0+N) mode.
The recoiling proton of the γ+p→ω+p reaction was identified
with an aerogel Cherenkov detector and the forward angle spectrometer MiniTAPS.
A first experiment on a carbon target has been performed as well a reference measurement on LH2.
The status of the analysis will be presented.
