Left: measured $\omega/\pi$ ratio as a function of transverse momentum in pp collisions at $\rso = 62$ and $200$ GeV . The smooth curve shows the estimated $\omega/\pi$ ratio in pp collisions at \rs. Right: estimated $\omega/\pi$ ratio as a function of the transverse momentum for 0--20\% central \pb collisions at \rsnn. The shaded regions in the two panels correspond to a $\pm20\%$ variation of the ratio, see text for details.
