Multi-strangeness Productions in Hadron Reactions

This study examines recent advancements in multi-strangeness production within hadron reactions. The authors introduce their recent research employing the effective Lagrangian method to analyze current experimental data. Notably, the focus is on the S = -2 channel due to its distinct characteristics compared to S = -1 channels. Specifically, we delve into reaction processes like K̄N → KΞ and K̄N → KΛΛ, offering potential insights into observing the H-dibaryon. Theoretically, the effective Lagrangian method is intensively employed for this purpose.
