Even though the predictions of the presently accepted models differ, the amount of experimental data does not allow for a determination of the best suited theory. The particular case of charmonium production in hadron collisions is an attractive test case as the charm is heavy enough to allow for perturbative calculations of the production process, and yet the cross sections involved are large enough so that events can be measured with good statistics. The data collected at the HERA-B detector after the HERA-II upgrade is analyzed and used to estimate the fraction of J/Ψ produced via radiative χ<sub>c</sub> decays. The result is compared to theoretical predictions and it is found to agree with calculations based on the color evaporation model and with the calculations using the non-relativistic quantum chromodynamics model. 2004 English text University of Cincinnati / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=ucin1100189506 http://rave.ohiolink.edu/etdc/view?acc_num=ucin1100189506 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
