Studying the $\omega$-mass in-medium in $\gamma +A\to {\pi }^0\gamma +X$ reactions

Abstract

Simulations based on a coupled-channel transport model have been performed to analyze the feasibility to study the in-medium $\omega$ mass exploiting the process $\gamma +A\to {\pi }^0\gamma +X$ for C, Ca and Nb nuclei. The distortions due to final-state interactions of the ${\pi }^0$ and background contributions from the reaction $\gamma +A\to {\pi }^0{\pi }^0+X$ are found to be small in the mass range of interest ($0.6<M_{{\pi }^0\gamma }<0.8$ GeV). Furthermore, the effect of the detector resolution on the ${\pi }^0\gamma$-mass determination is discussed.
