Title: Polarization of prompt J / ψ and Υ ( 1 S ) production in the color evaporation model

We calculate the polarization of prompt J/ψ and Υ(1S) production using the color evaporation model at leading order. We present the polarization parameter x F as a function of center of mass energy and rapidity in p+p collisions. We also compare the x F dependence to experimental results in p+Cu and π+W collisions, and predict the x F dependence in p+Pb collisions at fixed-target energies.
