### Abstract

We present the first calculation of longitudinal decorrelation of anisotropic flow at RHIC Beam Energy Scan (BES) energies using event-by-event viscous hydrodynamic model (vHLLE), with two different initial states (GLISSANDO2 and UrQMD) and hadronic cascade. We investigate the origin of the observed decorrelation by checking separately flow angle and flow magnitude decorrelation and by calculating decorrelation in the initial state eccentricity.

### List of changes

- added line in Section Model to emphasize the difference between initial state models UrQMD and Glissando
- added a sentence to the interpretation of Fig. 3 describing the other effect causing the difference between the models - switching from hadron cascade to fluid
