  We present a comprehensive study on the longitudinal flow decorrelation in
heavy-ion collisions at the RHIC Beam Energy Scan (BES) energies, spanning from
$\sqrt{s_{NN}}$ = 11.5 to 200 GeV in Au+Au collisions, using the A Multi-Phase
Transport (AMPT) model. Our investigation entails measuring the second and
third order factorization ratios ($r_{2}$ and $r_{3}$) across all these
energies. We observed that the decorrelation is stronger at lower energies
compared to higher collision energies, with this energy dependence trend being
more prominent in $r_{3}$. Additionally, we analyze the contributions of
flow-plane and flow magnitude decorrelation to the overall decorrelation
phenomenon. Notably, our findings reveal that flow plane decorrelation exhibits
a dominant contribution compared to flow magnitude decorrelation. Moreover, we
incorporate a recently proposed observable, the four particle cumulant
($T_{2}$), which remains resilient to non-flow effects and exhibits sensitivity
to different decorrelation patterns. Through the measurement of $T_{2}$, we
consistently observe an S-shaped or torqued decorrelation across all energy
ranges.
