Abstract

The properties of open strange meson K 1 ± in nuclear matter are estimated in the QCD sum rule approach. We obtain a relation between the in-medium mass and width of K 1 (K 1 + ) 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 K 1 meson is possible to be probed by using kaon beams at J-PARC. Such measurement together with that of K will shed light on how chiral symmetry is partially restored in nuclear matter.
