Significant medium--induced acoplanarity broadening is observed for large but not small recoil jet resolution parameter, corresponding to recoil jet yield enhancement up to a factor of $\\approx20$ for trigger--recoil azimuthal separation far from $\u03c0$. This phenomenology is indicative of the response of the Quark--Gluon Plasma to excitation, but not the scattering of jets off of its quasiparticles. The measurements are not well--described by current theoretical models which incorporate jet quenching.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.159953.v1/t1","@type":"Dataset","description":"Corrected Yield R=0.2 pi0+jet 10-15 pp at sqrt{s_{NN}}=200 GeV","name":"Table1"},{"@id":"https://doi.org/10.17182/hepdata.159953.v1/t2","@type":"Dataset","description":"Corrected Yield R=0.2 pi0+jet 15-20 pp at sqrt{s_{NN}}=200 GeV","name":"Table2"},{"@id":"https://doi.org/10.17182/hepdata.159953.v1/t3","@type":"Dataset","description":"Corrected Yield R=0.5 pi0+jet 10-15 pp at sqrt{s_{NN}}=200 GeV","name":"Table3"},{"@id":"https://doi.org/10.17182/hepdata.159953.v1/t4","@type":"Dataset","description":"Corrected Yield R=0.5 pi0+jet 15-20 pp at sqrt{s_{NN}}=200 GeV","name":"Table4"},{"@id":"https://doi.org/10.17182/hepdata.159953.v1/t5","@type":"Dataset","description":"Corrected Yield R=0.2 gamma+jet 10-15 pp at sqrt{s_{NN}}=200 GeV","name":"Table5"},{"@id":"https://doi.org/10.17182/hepdata.159953.v1/t6","@type":"Dataset","description":"Corrected Yield R=0.5 gamma+jet 10-15 pp at sqrt{s_{NN}}=200 GeV","name":"Table6"},{"@id":"https://doi.org/10.17182/hepdata.159953.v1/t7","@type":"Dataset","description":"Corrected Yield R=0.5 pi0+jet 10-15 AuAu 0-15% at sqrt{s_{NN}}=200 GeV","name":"Table7"},{"@id":"https://doi.org/10.17182/hepdata.159953.v1/t8","@type":"Dataset","description":"Corrected Yield R=0.2 pi0+jet 10-15 AuAu 0-15% at sqrt{s_{NN}}=200 GeV","name":"Table8"},{"@id":"https://doi.org/10.17182/hepdata.159953.v1/t9","@type":"Dataset","description":"Corrected Yield R=0.5 pi0+jet 15-20 AuAu 0-15% at sqrt{s_{NN}}=200 GeV","name":"Table9"},{"@id":"https://doi.org/10.17182/hepdata.159953.v1/t10","@type":"Dataset","description":"Corrected Yield R=0.2 pi0+jet 15-20 AuAu 0-15% at sqrt{s_{NN}}=200 GeV","name":"Table10"},{"@id":"https://doi.org/10.17182/hepdata.159953.v1/t11","@type":"Dataset","description":"Corrected Yield R=0.2 gamma+jet 10-15 AuAu 0-15% at sqrt{s_{NN}}=200 GeV","name":"Table11"},{"@id":"https://doi.org/10.17182/hepdata.159953.v1/t12","@type":"Dataset","description":"Corrected Yield R=0.5 gamma+jet 10-15 AuAu 0-15% at sqrt{s_{NN}}=200 GeV","name":"Table12"},{"@id":"https://doi.org/10.17182/hepdata.159953.v1/t13","@type":"Dataset","description":"IAA(\u0394\u03c6) R=0.5 gamma+jet 10-15 GeV/c","name":"Table13"},{"@id":"https://doi.org/10.17182/hepdata.159953.v1/t14","@type":"Dataset","description":"IAA(\u0394\u03c6) R=0.2 gamma+jet 10-15 GeV/c","name":"Table14"},{"@id":"https://doi.org/10.17182/hepdata.159953.v1/t15","@type":"Dataset","description":"IAA(\u0394\u03c6) R=0.5 pi0+jet 10-15 GeV/c","name":"Table15"},{"@id":"https://doi.org/10.17182/hepdata.159953.v1/t16","@type":"Dataset","description":"IAA(\u0394\u03c6) R=0.2 pi0+jet 10-15 GeV/c","name":"Table16"},{"@id":"https://doi.org/10.17182/hepdata.159953.v1/t17","@type":"Dataset","description":"IAA(\u0394\u03c6) R=0.5 pi0+jet 15-20 GeV/c","name":"Table17"},{"@id":"https://doi.org/10.17182/hepdata.159953.v1/t18","@type":"Dataset","description":"IAA(\u0394\u03c6) R=0.2 pi0+jet 15-20 GeV/c","name":"Table18"}],"identifier":[{"@type":"PropertyValue","propertyID":"HEPDataRecord","value":"https://www.hepdata.net/record/ins2919952?version=1"},{"@type":"PropertyValue","propertyID":"HEPDataRecordAlt","value":"https://www.hepdata.net/record/159953"}],"inLanguage":"en","name":"Measurement of medium-induced acoplanarity in central Au-Au and pp collisions at $\\sqrt{s_{\\rm NN}}=200$ GeV using direct-photon+jet and $\\pi^{0}$+jet correlations","provider":{"@type":"Organization","name":"HEPData"},"publisher":{"@type":"Organization","name":"HEPData"},"url":"https://www.hepdata.net/record/ins2919952?version=1","version":1}
