      abstract     = {The jet radial structure and particle transverse momentum
                      ($p_{\rm T}$) composition within jets are presented in
                      centrality-selected Pb–Pb collisions at $\sqrt{s_{\rm
                      NN}}$ = 2.76 TeV. Track-based jets, which are also called
                      charged jets, were reconstructed with a resolution parameter
                      of R=0.3 at midrapidity $|\eta_{\rm ch jet}|$ < 0.6 for
                      transverse momenta $p_{\rm T, ch jet}$ = 30 –120 GeV/c .
                      Jet–hadron correlations in relative azimuth and
                      pseudorapidity space ( Δφ,Δη ) are measured to study the
                      distribution of the associated particles around the jet axis
                      for different $p_{\rm T, assoc}$-ranges between 1 and 20
                      GeV/ c . The data in Pb–Pb collisions are compared to
                      reference distributions for pp collisions, obtained using
                      embedded PYTHIA simulations. The number of high-$p_{\rm T}$
                      associate particles (4 < $p_{\rm T, assoc}$ < 20 GeV/c) in
                      Pb–Pb collisions is found to be suppressed compared to the
                      reference by 30 to 10\%, depending on centrality. The radial
                      particle distribution relative to the jet axis shows a
                      moderate modification in Pb–Pb collisions with respect to
                      PYTHIA. High-$p_{\rm T}$ associate particles are slightly
                      more collimated in Pb–Pb collisions compared to the
                      reference, while low-$p_{\rm T}$ associate particles tend to
                      be broadened. The results, which are presented for the first
                      time down to $p_{\rm T, ch jet}$ = 30 GeV/c in Pb–Pb
                      collisions, are compatible with both previous
                      jet–hadron-related measurements from the CMS Collaboration
                      and jet shape measurements from the ALICE Collaboration at
                      higher $p_{\rm T}$, and add further support for the
                      established picture of in-medium parton energy loss.},
