\begin{document}$ p_{T} $\end{document} dispersion (\begin{document}$ p_{T}D $\end{document}) of inclusive jets (\begin{document}$ R=0.2 $\end{document}) in central Pb+Pb (0%–10%) collisions at \begin{document}$ \sqrt{s}=2.76 $\end{document} TeV. The partonic spectrum in the initial hard scattering of elementary collisions is obtained by an event generator POWHEG+PYTHIA, which matches the next-to-leading order (NLO) matrix elements with parton showering, and the energy loss of a fast parton traversing through hot/dense QCD medium is calculated using Monte Carlo simulation within the Higher-Twist formalism of jet quenching in heavy-ion collisions. We present model calculations of the normalized \begin{document}$ p_{T}D $\end{document} distributions of inclusive jets in p+p and central Pb+Pb collisions at \begin{document}$ \sqrt{s}=2.76 $\end{document} TeV, which offer good descriptions of ALICE measurements. It is shown that the \begin{document}$ p_{T}D $\end{document} distributions of inclusive jets in central Pb+Pb collisions shift significantly to a higher \begin{document}$ p_{T}D $\end{document} region relative to those in p+p collisions. Thus, the nuclear modification ratio of the \begin{document}$ p_{T}D $\end{document} distributions of inclusive jets is smaller than unity in the small \begin{document}$ p_{T}D $\end{document} region and larger than one in the large \begin{document}$ p_{T}D $\end{document} region. This behavior is caused by a more uneven \begin{document}$ p_T $\end{document} distribution for jet constituents as well as the fraction alteration of quark/gluon initiated jets in heavy-ion collisions. The difference in \begin{document}$ p_{T}D $\end{document} distribution between groomed and ungroomed jets in Pb+Pb collisions is also discussed."> <i>p</i><sub><i>T</i></sub> dispersion of inclusive jets in high-energy nuclear collisions -
