K0⁎(800) as a companion pole of K0⁎(1430)
We study the light scalar sector up to 1.8 GeV by using a quantum field theoretical approach which includes a single kaonic state in a Lagrangian with both derivative and non-derivative interactions. By performing a fit to πK phase shift data in the I=1/2, J=0 channel, we show that K0⁎(800) (or κ) e...
