"Charm Production at the Tevatron"

The upgraded Collider Detector at Fermilab (CDF II) has the capability to trigger on displaced tracks. This capability
in conjunction with the unprecedented integrated luminosity in excess of 1fb-1 opens a window of opportunity for 
detailed studies of charm hadron production.

CDF is now releasing first measurements of the prompt charm meson pair cross sections, which give access to QCD mechanisms
by which charm quarks are produced in proton anti-proton collisions.

Recent results on the spin alignment of J/Psi and Psi(2S) as well as on the relative production of the chi_c1(P1) and
chi_c2(1P) challenge our understanding of the fragmentation of charm quarks into charmonium states.
