    "abstract": "The momentum-space cut-off parameter $\\Lambda$ of hadronic vertex functions\nis studied in this paper. We use a composite model where we can measure the\ncontributions of intermediate particle propagations to $\\Lambda$. We show that\nin many cases a composite vertex function has a much smaller cut-off than its\nconstituent vertices, particularly when light constituents such as pions are\npresent in the intermediate state. This suggests that composite\nmeson-baryon-baryon vertex functions are rather soft, i.e., they have \\Lambda\nconsiderably less than 1 GeV. We discuss the origin of this softening of form\nfactors as well as the implications of our findings on the modeling of nuclear\nreactions.",
