Quarkonium wave functions at the origin: an update
arXiv:1904.11542
Abstract
Using a newly developed interquark potential, we tabulate values of the radial Schrödinger wave function or its first nonvanishing derivative at zero quark--antiquark separation, for , , and levels that lie below, or just above, the flavor threshold. These quantities are required inputs for evaluating quarkonium production cross sections.
