Characteristics of multi-particle production in proton-proton collisions at $\\sqrt{s}$=7 TeV are studied as a function of the charged-particle multiplicity, $N_{ch}$. The produced particles are separated into two classes: those belonging to jets and those belonging to the underlying event. Charged particles are measured with pseudorapidity |??|<2.4 and transverse momentum $p_T$ > 0.25 GeV/c. Jets are reconstructed from charged-particles only and required to have $p_T$ > 5 GeV/c. The distributions of jet $p_T$, average $p_T$ of charged particles belonging to the underlying event or to jets, jet rates, and jet shapes are presented as functions of $N_{ch}$ and compared to the predictions of the PYTHIA and HERWIG event generators. Predictions without multi-parton interactions fail completely to describe the $N_{ch}$-dependence observed in the data. For increasing $N_{ch}$, PYTHIA systematically predicts higher jet rates and harder $p_T$ spectra than seen in the data, whereas HERWIG shows the opposite trends. At the highest multiplicity, the data?EUR\"model agreement is worse for most observables, indicating the need for further tuning and/or new model ingredients.\nData taken from the RIVET analysis code.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.68128.v1/t1","@type":"Dataset","description":"Mean $p_T$, all charged particles.","name":"Table 1"},{"@id":"https://doi.org/10.17182/hepdata.68128.v1/t2","@type":"Dataset","description":"Mean $p_T$, UE charged particles.","name":"Table 2"},{"@id":"https://doi.org/10.17182/hepdata.68128.v1/t3","@type":"Dataset","description":"Mean $p_T$, in-jet charged particles.","name":"Table 3"},{"@id":"https://doi.org/10.17182/hepdata.68128.v1/t4","@type":"Dataset","description":"Mean $p_T$, leading in-jet charged particle.","name":"Table 4"},{"@id":"https://doi.org/10.17182/hepdata.68128.v1/t5","@type":"Dataset","description":"Mean $p_T$, charged particle jets, $p^{ch.jet}_T > 5$ GeV, $|\\eta^{ch.jet}| < 1.9$.","name":"Table 5"},{"@id":"https://doi.org/10.17182/hepdata.68128.v1/t6","@type":"Dataset","description":"Charged jet rate, $p^\\text{ch.jet}_T > 5$ GeV, $|\\eta^{ch.jet}| < 1.9$.","name":"Table 6"},{"@id":"https://doi.org/10.17182/hepdata.68128.v1/t7","@type":"Dataset","description":"Charged jet rate, $p^\\text{ch.jet}_T > 30$ GeV, $|\\eta^{ch.jet}| < 1.9$.","name":"Table 7"},{"@id":"https://doi.org/10.17182/hepdata.68128.v1/t8","@type":"Dataset","description":"Jet $p_T$ spectrum, $|\\eta^{ch.jet}| < 1.9$, $10 < N_\\text{ch} \\le 30$.","name":"Table 8"},{"@id":"https://doi.org/10.17182/hepdata.68128.v1/t9","@type":"Dataset","description":"Jet $p_T$ spectrum, $|\\eta^{ch.jet}| < 1.9$, $30 < N_\\text{ch} \\le 50$.","name":"Table 9"},{"@id":"https://doi.org/10.17182/hepdata.68128.v1/t10","@type":"Dataset","description":"Jet $p_T$ spectrum, $|\\eta^{ch.jet}| < 1.9$, $50 < N_\\text{ch} \\le 80$.","name":"Table 10"},{"@id":"https://doi.org/10.17182/hepdata.68128.v1/t11","@type":"Dataset","description":"Jet $p_T$ spectrum, $|\\eta^{ch.jet}| < 1.9$, $80 < N_\\text{ch} \\le 110$.","name":"Table 11"},{"@id":"https://doi.org/10.17182/hepdata.68128.v1/t12","@type":"Dataset","description":"Jet $p_T$ spectrum, $|\\eta^{ch.jet}| < 1.9$, $110 < N_\\text{ch} \\le 140$.","name":"Table 12"},{"@id":"https://doi.org/10.17182/hepdata.68128.v1/t13","@type":"Dataset","description":"Intrajet ring $p_{T}$ density, $10 < N_\\text{ch} \\le 30$.","name":"Table 13"},{"@id":"https://doi.org/10.17182/hepdata.68128.v1/t14","@type":"Dataset","description":"Intrajet ring $p_{T}$ density, $30 < N_\\text{ch} \\le 50$.","name":"Table 14"},{"@id":"https://doi.org/10.17182/hepdata.68128.v1/t15","@type":"Dataset","description":"Intrajet ring $p_{T}$ density, $50 < N_\\text{ch} \\le 80$.","name":"Table 15"},{"@id":"https://doi.org/10.17182/hepdata.68128.v1/t16","@type":"Dataset","description":"Intrajet ring $p_{T}$ density, $80 < N_\\text{ch} \\le 110$.","name":"Table 16"},{"@id":"https://doi.org/10.17182/hepdata.68128.v1/t17","@type":"Dataset","description":"Intrajet ring $p_{T}$ density, $110 < N_\\text{ch} \\le 140$.","name":"Table 17"}],"identifier":[{"@type":"PropertyValue","propertyID":"HEPDataRecord","value":"https://www.hepdata.net/record/ins1261026?version=1"},{"@type":"PropertyValue","propertyID":"HEPDataRecordAlt","value":"https://www.hepdata.net/record/68128"}],"inLanguage":"en","name":"Jet and underlying event properties as a function of particle multiplicity in proton-proton collisions at sqrt(s) = 7 TeV","provider":{"@type":"Organization","name":"HEPData"},"publisher":{"@type":"Organization","name":"HEPData"},"url":"https://www.hepdata.net/record/ins1261026?version=1","version":1}
