Kaonic production of \( \Lambda\)(1405) off deuteron target in chiral dynamics

Regular Article - Theoretical Physics

Abstract

The K--induced production of \( \Lambda\)(1405) is investigated in K-d\( \rightarrow\)\( \pi\)\( \Sigma\)n reactions based on coupled-channels chiral dynamics, in order to discuss the resonance position of the \( \Lambda\)(1405) in the \( \bar{{K}}\)N channel. We find that the K-d\( \rightarrow\)\( \Lambda\)(1405)n process favors the production of \( \Lambda\)(1405) initiated by the \( \bar{{K}}\)N channel. The present approach indicates that the \( \Lambda\)(1405) -resonance position is 1420MeV rather than 1405MeV in the \( \pi\)\( \Sigma\) invariant-mass spectra of K-d\( \rightarrow\)\( \pi\)\( \Sigma\)n reactions. This is consistent with an observed spectrum of the K-d\( \rightarrow\)\( \pi^{{+}}_{}\)\( \Sigma^{{-}}_{}\)n with 686-844MeV/c incident K- by bubble chamber experiments done in the 70s. Our model also reproduces the measured \( \Lambda\)(1405) production cross-section.
