Charmonium Production at High p(t) at RHIC

collisions at RHIC. We employ an earlier constructed 2-component approach for direct and regenerated charmonia which is fairly consistent with the centrality dependence of inclusive

J/\psi

yields at SPS and RHIC. Discrepancies with high-

p_t

data in

Cu

-

Cu

collisions are addressed by implementing effects of a finite formation time and an estimate of

B

meson feeddown, which largely resolve the problem. The sensitivity of the spectra to the Cronin effect and different in-medium dissociation rates is studied. The predicted elliptic flow in semicentral

Au

-

Au

collisions is rather small,

\sim

2-3%.
