Review of the (1405) A curious case of a strangeness resonance
M Mai - The European Physical Journal Special Topics, 2021 - Springer
During its long-lasting history, the Λ (1405) has become a benchmark for our understanding
of the SU (3) hadron dynamics. Starting with its theoretical prediction and later experimental …
