We report a transport model study of the rapidity even component of dipolar flow, , for identified charged hadrons at mid-rapidity in Au+Au collisions at GeV. The analysis is performed using the AMPT model. In addition, HIJING model is used to quantify residual non-flow contributions in . The of identified hadrons (, , and ) shows no significant difference between particles and anti-particles at GeV. However, a clear splitting between proton and anti-proton develops with decreasing beam energy, while no corresponding difference is observed for mesons ( and ). These results indicate that the proton-antiproton difference in is sensitive to baryon transport and antibaryon annihilation in the hadronic medium. Our study highlights the potential of identified-particle measurements at RHIC Beam Energy Scan energies as a novel probe of baryon stopping and the evolution of the hadronic medium.
