The angular correlation function (CF) in this analysis refers to the correlation of particles in the relative pseudorapidity and relative azimuthal angle. It is used to study properties of strongly interacting matter at relativistic energies. Recent results from the ALICE experiment at LHC show unexpected structures of CF in the proton-proton and antiproton-antiproton correlations. Also, results from the STAR experiment at RHIC on directed flow ($dv_{1}/dy$) for the net-baryons are intriguing.
The STAR capability of particle identification at midrapidity, paired with the data from broad energy range of Au+Au collisions in the Beam Energy Scan program, provides unique opportunity to investigate the phase diagram of strongly interacting matter through the CF analysis. In this talk, recent STAR experimental results from the Au+Au collisions at $\sqrt{s_{NN}} = 19.6$ GeV from the RHIC's Beam Energy Scan will be presented.
