Abstract：
Following the nonrelativistic QCD factorization scheme, by taking the latest available measurements of χ_bJ(3P) into consideration, we present an updated study on the yield and polarization of Y(1S, 2S, 3S) hadroproduction, and the fractions of χ_bJ(mP) feed-down in Y(nS) production at QCD next-to-leading order. In the fitting, three schemes are applied with different choices of χ_bJ(mP) feed-down ratios and NRQCD factorization scale. The results can explain the measurements of yield very well. The polarization puzzle to (3S) is now solved by considering the χ_bJ(3P) feed-down contributions. The ratio of σ[χ_b2(1P)]/σ[χ_b1(1P)] measured by the CMS experiment can also be reproduced in our prediction. Among the different schemes, the results show little difference, but there are sizeable differences for the fitted long-distance color-octet matrix elements. This may bring large uncertainties when the values are applied in theoretical predictions for other experiments such as those at ee, ep colliders.
