We study, at a qualitative level, production of jet pairs in ultrarelativistic nuclear collisions. We propose a new framework for combining $k_T$ factorization and a formalism for in-medium propagation of jet particles that takes into account stochastic transverse forces as well as medium-induced radiation. This approach allows to address dijet observables accounting for exact kinematics of the initial state. Using our framework, we provide a description of $R_{AA}$ data and study azimuthal decorrelations of the produced dijets. In particular, we find that the resulting dijet observables feature behavior deviating from that of jet pairs which undergo transverse-momentum broadening following the Gaussian distribution. We interpret this behavior as a consequence of dynamics encoded in the Blaizot–Dominguez–Mehtar-Tani–Iancu equation.
