QCD Sum Rule for Open Strange Meson $K_1^{\pm }$ in Nuclear Matter

Abstract

The properties of open strange meson $K_1^{\pm }$ 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 $K^{\ast }$ will shed light on how chiral symmetry is partially restored in nuclear matter.
