Three- and four-pion Bose-Einstein correlations are presented in pp, p-Pb, and Pb-Pb collisions at the LHC. We compare our measured four-pion correlations to the expectation derived from two- and three-pion measurements. Such a comparison provides a method to search for coherent pion emission. We also present mixed-charge correlations in order to demonstrate the effectiveness of several analysis procedures such as Coulomb corrections. Same-charge four-pion correlations in pp and p-Pb appear consistent with the expectations from three-pion measurements. However, the presence of non-negligible background correlations in both systems prevent a conclusive statement. In Pb-Pb collisions, we observe a significant suppression of three- and four-pion Bose-Einstein correlations compared to expectations from two-pion measurements. There appears to be no centrality dependence of the suppression within the 0-50% centrality interval. The origin of the suppression is not clear. However, by postulating either coherent pion emission or large multibody Coulomb effects, the suppression may be explained.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.72937.v1/t1","@type":"Dataset","description":"Mixed charge (- - - +) C4QS, a4QS, c4QS at low KT4 in pp collisions projected against Q4.","name":"Table 1"},{"@id":"https://doi.org/10.17182/hepdata.72937.v1/t2","@type":"Dataset","description":"Mixed charge (- - - +) C4QS, a4QS, c4QS at high KT4 in pp collisions projected against Q4.","name":"Table 2"},{"@id":"https://doi.org/10.17182/hepdata.72937.v1/t3","@type":"Dataset","description":"Mixed charge (- - - +) C4QS, a4QS, c4QS at low KT4 in pPb collisions projected against Q4.","name":"Table 3"},{"@id":"https://doi.org/10.17182/hepdata.72937.v1/t4","@type":"Dataset","description":"Mixed charge (- - - +) C4QS, a4QS, c4QS at high KT4 in pPb collisions projected against Q4.","name":"Table 4"},{"@id":"https://doi.org/10.17182/hepdata.72937.v1/t5","@type":"Dataset","description":"Mixed charge (- - - +) C4QS, a4QS, c4QS at low KT4 in PbPb collisions projected against Q4. 0-5% Centrality....","name":"Table 5"},{"@id":"https://doi.org/10.17182/hepdata.72937.v1/t6","@type":"Dataset","description":"Mixed charge (- - - +) C4QS, a4QS, c4QS at high KT4 in PbPb collisions projected against Q4. 0-5% Centrality....","name":"Table 6"},{"@id":"https://doi.org/10.17182/hepdata.72937.v1/t7","@type":"Dataset","description":"Mixed charge (- - + +) C4QS, a4QS, c4QS at low KT4 in pp collisions projected against Q4.","name":"Table 7"},{"@id":"https://doi.org/10.17182/hepdata.72937.v1/t8","@type":"Dataset","description":"Mixed charge (- - + +) C4QS, a4QS, c4QS at high KT4 in pp collisions projected against Q4.","name":"Table 8"},{"@id":"https://doi.org/10.17182/hepdata.72937.v1/t9","@type":"Dataset","description":"Mixed charge (- - + +) C4QS, a4QS, c4QS at low KT4 in pPb collisions projected against Q4.","name":"Table 9"},{"@id":"https://doi.org/10.17182/hepdata.72937.v1/t10","@type":"Dataset","description":"Mixed charge (- - + +) C4QS, a4QS, c4QS at high KT4 in pPb collisions projected against Q4.","name":"Table 10"},{"@id":"https://doi.org/10.17182/hepdata.72937.v1/t11","@type":"Dataset","description":"Mixed charge (- - + +) C4QS, a4QS, c4QS at low KT4 in PbPb collisions projected against Q4. 0-5% Centrality....","name":"Table 11"},{"@id":"https://doi.org/10.17182/hepdata.72937.v1/t12","@type":"Dataset","description":"Mixed charge (- - + +) C4QS, a4QS, c4QS at high KT4 in PbPb collisions projected against Q4. 0-5% Centrality....","name":"Table 12"},{"@id":"https://doi.org/10.17182/hepdata.72937.v1/t13","@type":"Dataset","description":"Same charge C3QS, and c3QS at low KT3 in pp collisions projected against Q3. 0-5% Centrality.
