Redistribution of energy at low-to-modest $p_T$ has been elusive to measure because of large anisotropic backgrounds. We report a data-driven method for background evaluation and subtraction, exploiting the away-side pseudorapidity gaps, to measure the jetlike correlation shape in Au+Au collisions at $\\sqrt{s_{_\\mathrm{NN}}}=200$ GeV with the STAR experiment. The correlation shapes, for trigger particle $p_T>3$ GeV/$c$ and various associated particle $p_T$ ranges within $0.5<p_T<10$ GeV/$c$, are consistent with Gaussians and their widths are found to increase with centrality. The results indicate jet broadening in the medium created in central heavy-ion collisions.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.95119.v1/t1","@type":"Dataset","description":"Distributions of the recoil momentum within 0.5&lt;\\eta&lt;1 (Px|_{0.5}^{1}) from high-pT trigger particles of 3&lt;pT_Trig&lt;10 GeV/c in 50-80% peripheral collisions","name":"Fig 2a"},{"@id":"https://doi.org/10.17182/hepdata.95119.v1/t2","@type":"Dataset","description":"Distributions of the recoil momentum within 0.5&lt;\\eta&lt;1 (Px|_{0.5}^{1}) from high-pT trigger particles of 3&lt;pT_Trig&lt;10 GeV/c in 0-10% central collisions","name":"Fig 2b"},{"@id":"https://doi.org/10.17182/hepdata.95119.v1/t3","@type":"Dataset","description":"Dihadron azimuthal correlations in close-region and far-region for 3&lt;pT_Trig&lt;10 GeV/c and 1&lt;pT_Assoc&lt;2 GeV/c in 10-30% Au+Au collisions at \\sNN=200 GeV","name":"Fig 3a"},{"@id":"https://doi.org/10.17182/hepdata.95119.v1/t4","@type":"Dataset","description":"The difference between close-region correlation and scaled far-region correlation","name":"Fig 3b"},{"@id":"https://doi.org/10.17182/hepdata.95119.v1/t5","@type":"Dataset","description":"Gaussian fit width to away-side jetlike correlations as a function of pT_Assoc and centrality in Au+Au collisions at \\sNN=200 GeV","name":"Fig 4"},{"@id":"https://doi.org/10.17182/hepdata.95119.v1/t6","@type":"Dataset","description":"Away-side jetlike correlation width as a function of pT_Assoc for 3&lt;pT_Trig&lt;10 GeV/c in 50-80% peripheral and top 10% central Au+Au...","name":"Fig 5a"},{"@id":"https://doi.org/10.17182/hepdata.95119.v1/t7","@type":"Dataset","description":"The difference between the correlation widths in central and peripheral collisions","name":"Fig 5b"}],"identifier":[{"@type":"PropertyValue","propertyID":"HEPDataRecord","value":"https://www.hepdata.net/record/ins1740989?version=1"},{"@type":"PropertyValue","propertyID":"HEPDataRecordAlt","value":"https://www.hepdata.net/record/95119"}],"inLanguage":"en","name":"Measurement of away-side broadening with self-subtraction of flow in Au+Au collisions at $\\sqrt{s_{_\\mathrm{NN}}}=200$ GeV","provider":{"@type":"Organization","name":"HEPData"},"publisher":{"@type":"Organization","name":"HEPData"},"url":"https://www.hepdata.net/record/ins1740989?version=1","version":1}
