报告摘要：There has been a resurgence of interest in the relativistic collisions of small systems after the surprising discovery of a long-range rapidity correlation in high-multiplicity proton-proton collisions at the LHC. The same signal was also seen in p+Pb collisions and d+Au collisions at RHIC which will follow up with p+Au and $^3$He-Au in the near future. Multi-particle correlation measurements suggest the presence of collective phenomena in these systems. One possible explanation is hydrodynamic flow. Another is intrinsic correlations generated from saturated gluonic matter within the proton. This talk will provide an overview of the experimental findings and interpretations.
