\begin{document}$b\bar{b}$\end{document} dijets in Pb + Pb collisions has been investigated by considering the in-medium evolution of heavy and light quarks simultaneously. The initial hard processes of inclusive b-jet and \begin{document}$b\bar{b}$\end{document} dijets production are described using a next-to-leading order (NLO) plus parton shower Monte Carlo (MC) event generator, SHERPA, which can be well matched with the experimental data in p + p collisions. The framework uses the Langevin transport model to describe the evolution of the bottom quark. Furthermore, the collisional energy loss and higher-twist description are considered to determine the radiative energy loss from both the bottom and light quarks. We compare the theoretical simulation of the inclusive jet and b-jet \begin{document}$R_{\rm AA}$\end{document} in the Pb + Pb collisions at \begin{document}$\sqrt{s_{ NN}}=2.76$\end{document} TeV with the experimental data and present the theoretical simulation of the momentum balance of the \begin{document}$b\bar{b}$\end{document} dijet in the Pb + Pb collisions at \begin{document}$5.02$\end{document} TeV along with recent CMS data for the first time. A similar trend to that seen in inclusive dijets is observed in \begin{document}$b\bar{b}$\end{document} dijets; the distribution of the production shifts to smaller \begin{document}$x_{\rm J}$\end{document} owing to the jet quenching effect. Finally, we report the prediction of the normalized azimuthal angle distribution of the \begin{document}$b\bar{b}$\end{document} dijet in the Pb + Pb collisions at \begin{document}$5.02$\end{document} TeV. The medium-induced energy loss effect of the \begin{document}$b\bar{b}$\end{document} dijets will generally suppress its production; however, the same side (\begin{document}$\Delta \phi \to 0$\end{document} region) suffers more energy loss than the far side (\begin{document}$\Delta \phi \to \pi$\end{document} region), thus leading to suppression on the same side and enhancement on the far side in the normalized azimuthal angle distribution in A + A collisions."> Transverse momentum balance and angular distribution of <inline-formula><tex-math id="M1-5">\begin{document}${{b\bar{b}}}$\end{document}</tex-math><alternatives><graphic xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="//www.macurncorp.com/hepnp/article/app/id/e2b64b6b-3466-4b11-b101-365fa938b677/CPC-2020-0253_M1-5.jpg"/><graphic xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="//www.macurncorp.com/hepnp/article/app/id/e2b64b6b-3466-4b11-b101-365fa938b677/CPC-2020-0253_M1-5.png"/></alternatives></inline-formula> dijets in Pb + Pb collisions -
