  Jet energy loss and single inclusive jet suppression in high-energy heavy-ion
collisions are studied within a pQCD parton model that includes both elastic
and radiative interactions between jet shower and medium partons as they
propagate through the quark-gluon plasma. The collisional energy loss of jets
with a given cone-size is found to be relatively small comparing with the
radiative energy loss. However the effect of transverse momentum broadening due
to elastic scattering is significant in the calculation of radiative energy
loss within the higher-twist formalism. The nuclear modification factors for
single inclusive jets with different cone-sizes are calculated and compared to
experimental data as measured by ALICE and ATLAS experiments in Pb+Pb
collisions at $\sqrt{s_{\rm NN}}=2.76$ TeV. Results on jet suppression in Pb+Pb
collisions at $\sqrt{s_{\rm NN}} = 5.02$ TeV are also presented.
