Abstract: (Springer)

Hadron production (

\pi ^\pm

, proton,

\Lambda

,

K_S^0

,

K^\pm

) in

\pi ^- + \textrm{C}

and

\pi ^- + \textrm{W}

collisions is investigated at an incident pion beam momentum of

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

\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.
