Abstract In heavy-ion reactions at RHIC energies the medium is baryon dilute but meson rich. Since by far the most abundant particles are pions, one can speak about pion matter. In [1, 2] we investigated medium modifications of mesons with open strangeness (K) and open charm (D) and the consequences of the corresponding resonances (φ and charmonia J/Ψ, Ψ ′ ,...) which are considered as promising probes for the fireball formed in ultrarelativistic reations. The in-medium mass operator of kaons can be expressed in terms of the πK forward scattering amplitudes. At the on-shell point the kaon self-energy, Σ(M 2 K, MK), the mass shift δMK, and the vector potential VK can be expressed in terms of the s-and p-wave scattering lengths and the s-wave effective ranges: Σ(M 2 K, MK) = −4πnv VK = − 2πnv Mπ + MK
