Quark number scaling of hadronic pT spectra and constituent quark degree of freedom in p–Pb collisions at sNN=5.02 TeV

We show that the experimental data of transverse momentum (pT) spectra of identified hadrons released recently by ALICE collaboration for p–Pb collisions at sNN=5.02 TeV exhibit a distinct universal behavior — the quark number scaling. We further show that the scaling is a direct consequence of quar...
