Signature of Λ(1405) resonance in K− +6Li reaction

Abstract

We investigate whether the mass and momentum spectra of emitted particles in [Formula: see text] reaction can be used for disentangling the nature of [Formula: see text](1405) and how the signature of the [Formula: see text](1405) resonance appears in the cross-sections of the kaon-lithium reaction on the physical real energy. We used different types of [Formula: see text] potentials to study the dependence of the results to the fundamental kaon-nucleon interaction. The momentum spectra are calculated for final pions and neutrons. The possibility of the observation of the [Formula: see text](1405) resonance in the mass spectra is studied. It was demonstrated that the [Formula: see text] mass and neutron momentum spectra are more suitable than the pion momentum spectra to see the trace of the [Formula: see text](1405) resonance and it is a useful tool for investigating the subthreshold behavior of the [Formula: see text] interaction.
