Description
We are proposing an experiment to study $\phi$ mass modification through $K^{+}K^{-}$ decay in p+A collisions at J-PARC. We exect to obtain several hundred thousands of $\phi \rightarrow K^{+}K^{-}$ decays in p+C and p+Cu collisions with 30 GeV proton beams. The $\phi$ mass modification is sensitive not only to the $K^{+}K^{-}$ modification but also to the branching ratio due to the small Q value. In this presentation, we discuss the physics of $\phi$ in nucleus, the design of the experiment, and the R&D status and plan of the kaon identification detectors.
