| Popis: | Physical review / D 59(9), 094023 (1999). doi:10.1103/PhysRevD.59.094023 The production of $\Upsilon$ mesons in fixed target $pN$ collisions is considered. It is shown that Non-Relativistic QCD predicts $\Upsilon$ states to be produced with sizeable transverse polarization. The possibility of a measurement of the $\Upsilon$ polarization at the HERA-$B$ experiment is discussed. Published by Inst., Woodbury, NY |
