Sumario: | Recent measurements performed at the LHC have revealed an unexpected presence of the near-side ridge and other signs of collectivity in p-Pb and pp collisions, referred to as small systems. Since in heavy-ion collisions these effects are caused by the formation and collective expansion of a quark-gluon plasma (QGP), such observations in small systems have triggered the ongoing debate about their origin. In this work, a brief overview of the latest ALICE results in small systems is presented. These include studies of two-particle angular correlations, charge balance functions, anisotropic flow and transverse momentum ($p_\text{{T}}$) spectra of identified hadrons. |
