Azimuthal angle ($\\Delta\\phi$) correlations are presented for a broad range of transverse momentum ($0.4 < p_{\\rm T} < 10$~GeV/$c$) and centrality (0-92%) selections for charged hadrons from di-jets in Au+Au collisions at $\\sqrt{s_{\\rm{NN}}}$ = 200 GeV. With increasing $p_{\\rm T}$, the away-side $\\Delta\\phi$ distribution evolves from a broad and relatively flat shape to a concave shape, then to a convex shape. Comparisons to $p+p$ data suggest that the away-side distribution can be divided into a partially suppressed \"head\" region centered at $\\Delta\\phi\\sim\\pi$, and an enhanced \"shoulder\" region centered at $\\Delta\\phi\\sim \\pi\\pm 1.1$. The $p_{\\rm T}$ spectrum for the associated hadrons in the head region softens toward central collisions. The spectral slope for the shoulder region is independent of centrality and trigger $p_{\\rm T}$. The properties of the near-side distributions are also modified relative to those in $p+p$ collisions, reflected by the broadening of the jet shape in $\\Delta\\phi$ and $\\Delta\\eta$, and an enhancement of the per-trigger yield. However, these modifications seem to be limited to $p_{\\rm T}\\lesssim4$ GeV/$c$, above which both the hadron pair shape and per-trigger yield become similar to $p+p$ collisions. These observations suggest that both the away- and near-side distributions contain a jet fragmentation component which dominates for $p_{\\rm T}\\gtrsim5$ GeV and a medium-induced component which is important for $p_{\\rm T}\\lesssim4$ GeV/$c$. We also quantify the role of jets at intermediate and low $p_{\\rm T}$ through the yield of jet-induced pairs in comparison to binary scaled $p+p$ pair yield. The yield of jet-induced pairs is suppressed at high pair proxy energy (sum of the $p_{\\rm T}$ magnitudes of the two hadrons) and is enhanced at low pair proxy energy. The former is consistent with jet quenching; the latter is consistent with the enhancement of soft hadron pairs due to transport of lost energy to lower $p_{\\rm T}$.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.96764.v2/t1","@type":"Dataset","description":"Per-trigger yield versus $\\Delta\\phi$ for various trigger and partner $p_T$ ($p^a_T \\otimes p^b_T$), arranged by increasing pair proxy energy (sum...","name":"Figure 6, pp, part 2/2"},{"@id":"https://doi.org/10.17182/hepdata.96764.v2/t2","@type":"Dataset","description":"Per-trigger yield versus $\\Delta\\phi$ for various trigger and partner $p_T$ ($p^a_T \\otimes p^b_T$), arranged by increasing pair proxy energy (sum...","name":"Figure 6, pp, part 1/2"},{"@id":"https://doi.org/10.17182/hepdata.96764.v2/t3","@type":"Dataset","description":"Per-trigger yield versus $\\Delta\\phi$ for various trigger and partner $p_T$ ($p^a_T \\otimes p^b_T$), arranged by increasing pair proxy energy (sum...","name":"Figure 6, AuAu, part 1/2"},{"@id":"https://doi.org/10.17182/hepdata.96764.v2/t4","@type":"Dataset","description":"Per-trigger yield versus $\\Delta\\phi$ for various trigger and partner $p_T$ ($p^a_T \\otimes p^b_T$), arranged by increasing pair proxy energy (sum...","name":"Figure 6, AuAu, part 2/2"},{"@id":"https://doi.org/10.17182/hepdata.96764.v2/t5","@type":"Dataset","description":"RHS versus $p^b_T$ for p + p collisions for four trigger selections.","name":"Figure 7, p + p collisions"},{"@id":"https://doi.org/10.17182/hepdata.96764.v2/t6","@type":"Dataset","description":"RHS versus $p^b_T$ for Au + Au collisions for four trigger selections.","name":"Figure 7, Au + Au collisions"},{"@id":"https://doi.org/10.17182/hepdata.96764.v2/t7","@type":"Dataset","description":"RHS versus $N_{part}$ for 2-3 $\\otimes$ 2-3 GeV/$c$.
