Abstract

Hadron production ( $π^{\pm}$ $\pi ^\pm$ , proton, $Λ$ $\Lambda$ , $K_{S}^{0}$ $$K_S^0$$ , $K^{\pm}$ $K^\pm$ ) in $π^{-} + C$ $\pi ^- + \textrm{C}$ and $π^{-} + W$ $\pi ^- + \textrm{W}$ collisions is investigated at an incident pion beam momentum of $1.7 GeV / c$ $1.7~\textrm{GeV}/c$ . This comprehensive set of data measured with HADES at SIS18/GSI significantly extends the existing world data on hadron production in pion induced reactions and provides a new reference for models that are commonly used for the interpretation of heavy-ion collisions. The measured inclusive differential production cross-sections are compared with state-of-the-art transport model (GiBUU, SMASH) calculations. The (semi-) exclusive channel $π^{-} + A \to Λ + K_{S}^{0} + X$ $\pi ^- + A \rightarrow \Lambda + K_S^0 +X$ , in which the kinematics of the strange hadrons are correlated, is also investigated and compared to a model calculation. Agreement and remaining tensions between data and the current version of the considered transport models are discussed.
