✦ Synopsis

We report lattice QCD results of scattering amplitudes of πK system for both I = 3/2 and 1/2 channles. The lattice simulations are made in the quenched approximation at β = 2.23 on a 12 3 × 24 lattice. The hopping parameters of κ ud = 0.1570, 0.1580 and κ s = 0.1546, 0.1570 are used. A clear difference of energy shift is found between I=3/2 and I=1/2 channels.

Using the concept of collision time (time delay) introduced by Eisenbud and Wigner and its connection to on-shell intermediate unstable states, we study mesonic resonances in ππ and πK scattering. The time-delay method proves its usefulness by revealing the spectrum of the well known ρ-and K \* -mes
