Title: Probing heavy quarkonium production mechnism: χ{sub c} polarization

The necesscity of the color-octet mechanism in describing heavy quarkonium production is a longstanding puzzle. Compared to the yields of heavy quarkonium, its polarizations should be a sensitive observable to pin down the color-octet contributions. In this talk, I will focus on the χ{sub c} polarization in hadroproduction processes, which may provide a unique test for the color-octet mechanism in nonrelativistic QCD.
