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. (C) 2019 The Authors. Published by Elsevier B.V.
