The polarization of inclusive $\ensuremath{\Upsilon}(\mathrm{nS})$ at the Fermilab Tevatron is calculated within the nonrelativistic QCD factorization framework. We use a recent determination of the NRQCD matrix elements from fitting the CDF data on bottomonium production from run IB of the Tevatron. The result for the polarization of $\ensuremath{\Upsilon}(1S)$ integrated over …
