We are developing a linac dedicated to the muon acceleration. It enables us to measure the muon anomalous magnetic moment with an accuracy of 0.1 ppm and search for electric dipole moment with a sensitivity of 10 $^{-21}$ cm to explore beyond Standard Model of elementary particle physics. As a first step for demonstration of the muon acceleration, we are developing the source of slow muon with which RFQ acceleration is conducted. This paper describes status of these developments.

We have carried out an experimental search for the simplest kaonic nucleus, $K^{-}pp$ , by using the $d(pi^{+},K^{+})$ reaction at = 1.69 GeV/. The differential cross section of this reaction with covering a wide missing-mass range from the production threshold to the (1405)/(1385) region has been measured for the first time. The inclusive missing-mass shape of the and production region was understood with a simple quasi-free picture except for an enhancement at 2.13 GeV/ $c^{2}$ due to a cusp. An obtained peak attributed to $Y^{*}$ production was significantly shifted to the low mass side compared with the simulation by -24 MeV/ $c^{2}$ .
