Query: Counting valence quarks at RHIC and LHC   We consider the Nuclear Modification Ratios in heavy ion collisions, R_CP and
R_AA, in the region of intermediate transverse momentum, and study the
dependency upon the constituent quark composition of the observed hadron.
Adopting a two component recombination/fragmentation model, validated by
experimental information from STAR and PHENIX, we show that a clear distinction
is predicted for the f0(980) between the assumptions of $s\bar s$ or
diquark-antidiquark content.
