We address the puzzle of {sigma}({chi}{sub c1})/{sigma}({chi}{sub c2}) ratio at the collider and fixed-target experiments. We consider several factors that can affect the predicted ratio of the production rates. In particular, we discuss the effect of {chi}{sub cJ} polarization, the effect of including next-to-leading order contributions, and the effect of probably different {chi}{sub c1} and {chi}{sub c2} wave functions.
