### Description

We discuss production of vector $K^∗$ and $D^∗$ mesons in $\pi^− p$ interaction
with their subsequent decay into pseudoscalar $K + \pi$ and $D + \pi$ mesons,
respectively. Our consideration is based on modified quark-gluon string model
which includes spin variables and allows to determine decay distributions
of the outgoing pseudoscalars. These distributions are sensitive to the vector
meson production mechanism and can be used for its determination. We find the
relative importance of vector-meson Reggeon exchange to others for the cross
sections. Result of present study may be used in projects of future experimental
programs with the pion beams (for instance, at J-PARC facility).
