We propose to study in-medium mass modification of the φ meson using the formation of φ meson bound state. We demonstrate that a clear missing-mass spectrum can be obtained efficiently by (p, φ) spectroscopy together with the Λ tagging, using the primary reaction channel pp → φφ. A systematic study over several nuclear targets will yield a unique, definitive and precise determination of the in-medium mass modification of the vector meson φ(ss).
