Description
We propose in this talk to investigate the QCD dynamics at sPHENIX experiment through two studies:
First, the internal jet structure study provides information about the hadronization process in non-perturbative QCD dynamics. The non-perturbative flavor correlation between pairs of leading and next-to-leading charged hadrons is proposed. The correlation ratio observable $r_{c}$ for protons, kaons and pions for various kinematic variables is investigated.
Second, the Drell-Yan (DY) process is also discussed as a probe of transport properties of the cold nuclear matter (CNM). The DY events extraction involves a precise knowledge of QCD background participating in the dilepton invariant mass spectrum. A fit of this one, including open-charm, open-bottom, charmonium and bottomonium simulations, is shown. CNM effects are investigated via the rapidity (y) and transverse momentum ($p_{\perp}$) distributions of the DY dilepton pair.
