Abstract
The properties of open strange meson in nuclear matter are estimated in the QCD sum rule approach. We obtain a relation between the in-medium mass and width of () in nuclear matter, and show that the upper limit of the mass shift is as large as -249 (-35) MeV. The spectral modification of the meson is possible to be probed by using kaon beams at J-PARC. Such measurement together with that of will shed light on how chiral symmetry is partially restored in nuclear matter.
