英文摘要: The number of constituent quarks (NCQ) scaling for hadrons and the number of constituent nucleons (NCN) scaling for light nuclei are proposed for nuclear modification factors (R-cp) of hadrons and light nuclei, respectively, according to the experimental investigations in relativistic heavy-ion collisions. Based on the coalescence mechanism the scalings are performed for pions and protons at the quark level, and for light nuclei d((d) over bar) and He-3 at the nucleonic level, respectively, formed in Au + Au and Pb + Pb collisions, and a nice scaling behaviour emerges. The NCQ or NCN scaling law of Rcp can be, respectively, taken as a probe for the quark or nucleon coalescence mechanism for the formation of hadron or light nuclei in relativistic heavy-ion collisions.
