Is the Pentaquark the Only Justification for Research on KN Physics ?

Abstract

The talk is intended to motivate the use of DA$\Phi$NE--2 running at the $\varphi$ peak as an intense, clean source of low--momentum charged and neutral kaons. It covers a few open problems still unsolved after more than twenty--five years and the physics (some of it still novel) that could be learned only in this way. And, of course, the answer to the above question is {\sl NO}.
