    "abstract": "We argue that the non-perturbative Schwinger mechanism may play an important\nrole in the hadronic production of charm. We present a flux tube model which\nassumes that the colliding hadrons become color charged because of gluon\nexchange, and that a single non-elementary flux tube is built up as they\nrecede. The strong chromoelectric field inside this tube creates quark pairs\n(including charmed ones) and the ensuing color screening breaks the tube into\nexcited hadronic clusters. On their turn these clusters, or `fireballs\u0027, decay\nstatistically into the final hadrons. The model is able to account for the soft\nproduction of charmed, strange and lighter hadrons within a unified framework.",
