the elliptic azimuthal anisotropy coefficient(v_(2))of the identified particles at midrapidity(|η|s investigated in p-Pb collisions at√s_(NN)=5.02 teV using a multi-phase transport model(AMPt).the calculations of differential v_(2)based on the advanced flow extraction method of light flavor hadrons(pions,kaons,protons,andΛ)in small collision systems were extended to a wider transverse momentum(p_(t))range of up to 8 GeV/c for the first *** string-melting version of the AMPt model provides a good description of the measured p_(t)-differential v_(2)of the mesons but exhibits a slight deviation from the baryon v_(2).In addition,we observed the features of mass ordering at low p_(t)and the approximate number-of-constituentquark(NCQ)scaling at intermediate p_(t).Moreover,we demonstrate that hadronic rescattering does not have a significant impact on v_(2)in p-Pb collisions for different centrality selections,whereas partonic scattering dominates in generating the elliptic anisotropy of the final *** study provides further insight into the origin of collective-like behavior in small collision systems and has referential value for future measurements of azimuthal anisotropy.
