The event activity, quantified by charged-particle number and summed-$p_{\\rm T}$ densities, is measured\nas a function of the leading-particle transverse momentum ($p_{\\rm T}^{\\rm trig}$). These quantities are studied in three azimuthal-angle regions relative to the leading particle in the event: toward, away, and transverse. Results are presented for\nthree different $p_{\\rm T}$ thresholds (0.15, 0.5 and 1 GeV/$c$) at mid-pseudorapidity ($|\\\\eta|<0.8$).\nThe event activity in the transverse region, which is the most sensitive to the underlying event, exhibits similar behaviour in both pp and p-Pb\ncollisions, namely, a steep increase with $p_{\\rm T}^{\\rm trig}$ for low $p_{\\rm T}^{\\rm trig}$, followed by a saturation at $p_{\\rm T}^{\\rm trig} \\approx 5$ GeV/$c$. The results from pp collisions are\ncompared with existing measurements at other centre-of-mass energies. The quantities in the toward and away regions are also analyzed after\nthe subtraction of the contribution measured in the transverse region. The remaining jet-like particle densities are consistent in pp and p-Pb\ncollisions for $p_{\\rm T}^{\\rm trig}>10$ GeV/$c$, whereas for lower  $p_{\\rm T}^{\\rm trig}$ values\nthe event activity is slightly higher in pPb than in pp collisions. The measurements are compared with predictions from the Monte Carlo event generators.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.133032.v1/t1","@type":"Dataset","description":"Fig. 4: Number density $N_{\\rm ch}$ (left) and $\\Sigma p_{\\rm T}$ (right) distributions as a function of $p_{\\rm T}^{\\rm trig}$...","name":"Table 1"},{"@id":"https://doi.org/10.17182/hepdata.133032.v1/t2","@type":"Dataset","description":"Fig. 5: Number density $N_{\\rm ch}$ (left) and $\\Sigma p_{\\rm T}$ (right) distributions as a function of $p_{\\rm T}^{\\rm trig}$...","name":"Table 2"},{"@id":"https://doi.org/10.17182/hepdata.133032.v1/t3","@type":"Dataset","description":"Fig. 6a: Number density $N_{\\rm ch}$ (left) and $\\Sigma p_{\\rm T}$ (right) distributions as a function of $p_{\\rm T}^{\\rm trig}$...","name":"Table 3"},{"@id":"https://doi.org/10.17182/hepdata.133032.v1/t4","@type":"Dataset","description":"Fig. 6b: Number density $N_{\\rm ch}$ (left) and $\\Sigma p_{\\rm T}$ (right) distributions as a function of $p_{\\rm T}^{\\rm trig}$...","name":"Table 4"},{"@id":"https://doi.org/10.17182/hepdata.133032.v1/t5","@type":"Dataset","description":"Fig. 7a: $$ as a function of $p_{\\rm T}^{\\rm trig}$ in Toward (left) and Away (right) regions after the...","name":"Table 5"},{"@id":"https://doi.org/10.17182/hepdata.133032.v1/t6","@type":"Dataset","description":"Fig. 7b: $$ as a function of $p_{\\rm T}^{\\rm trig}$ in Toward (left) and Away (right) regions after the...","name":"Table 6"},{"@id":"https://doi.org/10.17182/hepdata.133032.v1/t7","@type":"Dataset","description":"Fig. A1: Number density $N_{\\rm ch}$ (left) and $\\Sigma p_{\\rm T}$ (right) distributions as a function of $p_{\\rm T}^{\\rm trig}$...","name":"Table 7"},{"@id":"https://doi.org/10.17182/hepdata.133032.v1/t8","@type":"Dataset","description":"Fig. A2: Number density $N_{\\rm ch}$ (left) and $\\Sigma p_{\\rm T}$ (right) distributions as a function of $p_{\\rm T}^{\\rm trig}$...","name":"Table 8"},{"@id":"https://doi.org/10.17182/hepdata.133032.v1/t9","@type":"Dataset","description":"Fig. A3: Number density $N_{\\rm ch}$ (left) and $\\Sigma p_{\\rm T}$ (right) distributions as a function of $p_{\\rm T}^{\\rm trig}$...","name":"Table 9"},{"@id":"https://doi.org/10.17182/hepdata.133032.v1/t10","@type":"Dataset","description":"Fig. A4: Number density $N_{\\rm ch}$ (left) and $\\Sigma p_{\\rm T}$ (right) distributions as a function of $p_{\\rm T}^{\\rm trig}$...","name":"Table 10"}],"identifier":[{"@type":"PropertyValue","propertyID":"HEPDataRecord","value":"https://www.hepdata.net/record/ins2071174?version=1"},{"@type":"PropertyValue","propertyID":"HEPDataRecordAlt","value":"https://www.hepdata.net/record/133032"}],"inLanguage":"en","name":"Underlying-event properties in pp and p$-$Pb collisions at $\\sqrt{s_{\\rm NN}} = 5.02$ TeV","provider":{"@type":"Organization","name":"HEPData"},"publisher":{"@type":"Organization","name":"HEPData"},"url":"https://www.hepdata.net/record/ins2071174?version=1","version":1}
