VOLUME 88 | ISSUE 11 | PAGE 825 Production and polarization of Υ mesons in the kt-factorization approach in more detail S. P. Baranov, N. P. Zotov* 1) P.N. Lebedev Institute of Physics RAS, 119991 Moscow, Russia *D.V. Skobeltzyn Institute of Nuclear Physics, 119991 Moscow, Russia PACS: 12.38.Bx, 13.85.Ni, 14.40.Gx Abstract In the framework of the kt-factorization approach, the production and polarization of Υ mesons at the Fermilab Tevatron is considered, and a comparision of the calculated double differential distributions and spin alignment parameter α with the D0 experimental data is shown. We argue that measuring the double differential cross section and the polarization of upsilonium states can serve as a crucial test discriminating two competing theoretical approaches to the parton dynamics in QCD.
