The mass shift of the vector mesons in nuclei is known to be a powerful tool for investigating the mechanism of generating hadron mass from the QCD vacuum. The mechanism is known to be the spontaneous breaking of chiral symmetry. In 2007, KEK-PS E325 experiment reported about 3. 4 % mass reduction of the φ{symbol} meson in medium-heavy nuclei (Cu). This result is possibly one of the indications of the partial restoration of chiral symmetry in nuclei, however, unfortunately it is hard to make strong conclusions from the data. One of the ways to conclude the strength of the φ{symbol} meson mass shift in nuclei will be by trying to produce only slowly moving φ{symbol} mesons where the maximum nuclear matter effect can be probed. The observed mass reduction of the φ{symbol} meson in the nucleus can be translated as the existence of an attractive force between φ{symbol} meson and nucleus. Thus, one of the extreme conditions that can be achieved in the laboratory is indeed the formation of a φ{symbol}-nucleus bound state, where the φ{symbol} meson is "trapped" in the nucleus. The purpose of the experiment is to search for a φ{symbol}-nucleus bound state and measure the binding energy of the system. We will demonstrate that a completely background-free missing-mass spectrum can be obtained efficiently by (p̄,φ{symbol}) spectroscopy together with K+Λ tagging, using the primary reaction channel p̄p → φ{symbol}φ{symbol}. This paper gives an overview of the physics motivation and the detector concept, and explains the direction of the initial research and development effort. © 2012 Springer Science+Business Media B.V.
