 Evolution of the longitudinal and azimuthal structure of the near-side peak in Pb–Pb collisions at $\sqrt{s_{\rm NN}}=2.76$ TeV / Adam, Jaroslav (Prague, Tech. U.) ; Adamova, Dagmar (Rez, Nucl. Phys. Inst.) ; Aggarwal, Madan Mohan (Panjab U.) ; Aglieri Rinella, Gianluca (CERN) ; Agnello, Michelangelo (INFN, Turin ; Turin Polytechnic) ; Agrawal, Neelima (Indian Inst. Tech., Mumbai) ; Ahammed, Zubayer (Calcutta, VECC) ; Ahmad, Shakeel (Aligarh Muslim U.) ; Ahn, Sang Un (KISTI, Daejeon) ; Aiola, Salvatore (Yale U.) et al. In two-particle angular correlation measurements, jets give rise to a near-side peak, formed by particles associated to a higher $p_{\mathrm{T}}$ trigger particle. Measurements of these correlations as a function of pseudorapidity ($\Delta\eta$) and azimuthal differences ($\Delta\varphi$) are used to extract the centrality and $p_{\mathrm{T}}$ dependence of the shape of the near-side peak in the $p_{\mathrm{T}}$ range $1 < p_{\mathrm{T}} <$ 8 GeV/c in Pb--Pb and pp collisions at $\sqrt{s_{\mathrm{NN}}}$ = 2.76 TeV.

 Decomposing transverse momentum balance contributions for quenched jets in PbPb collisions at $\sqrt{s_\mathrm{NN}} =$ 2.76 TeV / CMS Collaboration Interactions between jets and the quark-gluon plasma produced in heavy ion collisions are studied via the angular distributions of summed charged-particle transverse momenta ($p_{\mathrm{T}}$) with respect to both the leading and subleading jet axes in high-$p_{\mathrm{T}}$ dijet events.
