Production of π− mesons in CTa interactions at a momentum of 4.2 GeV/c per nucleon

New experimental data on π − -meson production in interactions between carbon and tantalum nuclei at amomentumof 4.2 GeV/ c per nucleon are presented. These results are compared with predictions based of themodel of quark-gluon strings (QGS) that is adapted to intermediate energies ( ≤ 4 GeV). It is...

Description
Summary:New experimental data on π − -meson production in interactions between carbon and tantalum nuclei at amomentumof 4.2 GeV/ c per nucleon are presented. These results are compared with predictions based of themodel of quark-gluon strings (QGS) that is adapted to intermediate energies ( ≤ 4 GeV). It is shown that the QGS model only qualitatively reproduces the behavior of experimental kinematical features of π − mesons.
