The momentum ratio of the two leading partons, resolved as subjets, provides information about the parton shower evolution. This substructure observable, known as the splitting function, reflects the process of a parton splitting into two other partons and has been measured for jets with transverse momentum between 140 and 500 GeV, in pp and PbPb collisions at a center-of-mass energy of 5.02 GeV per nucleon pair. In central PbPb collisions, the splitting function indicates a more unbalanced momentum ratio, compared to peripheral PbPb and pp collisions. The measurements are compared to various predictions from event generators and analytical calculations.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.79666.v1/t1","@type":"Dataset","description":"Groomed jet energy fraction in pp and PbPb collisions for jets with PTJET 160-180 GeV.","name":"Table 1"},{"@id":"https://doi.org/10.17182/hepdata.79666.v1/t2","@type":"Dataset","description":"Self-normalized zg distribution in pp collisions for jets with PTJET 160-180 GeV.","name":"Table 2"},{"@id":"https://doi.org/10.17182/hepdata.79666.v1/t3","@type":"Dataset","description":"Self-normalized zg distributions in PbPb and smeared pp collisions in the 50-80 centrality event class for jets with PTJET 160-180...","name":"Table 3"},{"@id":"https://doi.org/10.17182/hepdata.79666.v1/t4","@type":"Dataset","description":"Self-normalized zg distributions in PbPb and smeared pp collisions in the 30-50 centrality event class for jets with PTJET 160-180...","name":"Table 4"},{"@id":"https://doi.org/10.17182/hepdata.79666.v1/t5","@type":"Dataset","description":"Self-normalized zg distributions in PbPb and smeared pp collisions in the 10-30 centrality event class for jets with PTJET 160-180...","name":"Table 5"},{"@id":"https://doi.org/10.17182/hepdata.79666.v1/t6","@type":"Dataset","description":"Self-normalized zg distributions in PbPb and smeared pp collisions in the 0-10 centrality event class for jets with PTJET 160-180...","name":"Table 6"},{"@id":"https://doi.org/10.17182/hepdata.79666.v1/t7","@type":"Dataset","description":"Ratio of zg distributions in PbPb and smeared pp collisions in the 50-80 centrality event class for jets with PTJET...","name":"Table 7"},{"@id":"https://doi.org/10.17182/hepdata.79666.v1/t8","@type":"Dataset","description":"Ratio of zg distributions in PbPb and smeared pp collisions in the 30-50 centrality event class for jets with PTJET...","name":"Table 8"},{"@id":"https://doi.org/10.17182/hepdata.79666.v1/t9","@type":"Dataset","description":"Ratio of zg distributions in PbPb and smeared pp collisions in the 10-30 centrality event class for jets with PTJET...","name":"Table 9"},{"@id":"https://doi.org/10.17182/hepdata.79666.v1/t10","@type":"Dataset","description":"Ratio of zg distributions in PbPb and smeared pp collisions in the 0-10 centrality event class for jets with PTJET...","name":"Table 10"},{"@id":"https://doi.org/10.17182/hepdata.79666.v1/t11","@type":"Dataset","description":"Ratio of zg distributions in PbPb and smeared pp collisions in the 10% most central events for jets with PTJET...","name":"Table 11"},{"@id":"https://doi.org/10.17182/hepdata.79666.v1/t12","@type":"Dataset","description":"Ratio of zg distributions in PbPb and smeared pp collisions in the 10% most central events for jets with PTJET...","name":"Table 12"},{"@id":"https://doi.org/10.17182/hepdata.79666.v1/t13","@type":"Dataset","description":"Ratio of zg distributions in PbPb and smeared pp collisions in the 10% most central events for jets with PTJET...","name":"Table 13"},{"@id":"https://doi.org/10.17182/hepdata.79666.v1/t14","@type":"Dataset","description":"Ratio of zg distributions in PbPb and smeared pp collisions in the 10% most central events for jets with PTJET...","name":"Table 14"},{"@id":"https://doi.org/10.17182/hepdata.79666.v1/t15","@type":"Dataset","description":"Ratio of zg distributions in PbPb and smeared pp collisions in the 10% most central events for jets with PTJET...","name":"Table 15"},{"@id":"https://doi.org/10.17182/hepdata.79666.v1/t16","@type":"Dataset","description":"Ratio of zg distributions in PbPb and smeared pp collisions in the 10% most central events for jets with PTJET...","name":"Table 16"}],"identifier":[{"@type":"PropertyValue","propertyID":"HEPDataRecord","value":"https://www.hepdata.net/record/ins1620905?version=1"},{"@type":"PropertyValue","propertyID":"HEPDataRecordAlt","value":"https://www.hepdata.net/record/79666"}],"inLanguage":"en","name":"Measurement of the splitting function in pp and PbPb collisions at $\\sqrt{s_{_{\\mathrm{NN}}}}=$ 5.02 TeV","provider":{"@type":"Organization","name":"HEPData"},"publisher":{"@type":"Organization","name":"HEPData"},"url":"https://www.hepdata.net/record/ins1620905?version=1","version":1}
