Ultrarelativistic heavy-ion collisions provide insights into the early stages of the expanding universe. The quark-gluon plasma (QGP) is a unique state of matter formed in such high-energy interactions. The existence of this hot and dense strongly interacting medium is associated with several signatures, such as jet suppression and the collective behaviour of the final state particles. The ALICE, ATLAS and CMS Collaborations are actively investigating these properties in various configurations. Proton-nucleus and high-multiplicity proton-proton collisions are considered as small systems and are used as benchmarks for the interpretation of heavy-ion collisions. The aim of this paper is to summarise recent measurements of the jet-related QGP signatures observed in small systems.
