Low Energy Kaon Physics at Da$Φ$NE

Abstract

DA$Φ$NE $e^+ e^-$ collider is an abundant source of low energy $K \bar K$ pairs suitable to explore different fields of non perturbative QCD regime. Two different experiments, DEAR and FINUDA, using different experimental techniq ues are trying to shed new light on the strong interaction at the nucleon scale by producing high precision results at this energy range. The DEAR experiment is studying kaonic atoms in order to determine antikaon-nucleon scattering lengths. FINUDA aims to produce hypernuclei to study nuclear structure and $Λ$-N interaction.
