Abstract
Boltzmann–Gibbs blast-wave model was used to analyze the transverse momentum distributions of strange hadrons ([Formula: see text], [Formula: see text], [Formula: see text], [Formula: see text], [Formula: see text], [Formula: see text], [Formula: see text], [Formula: see text], [Formula: see text], and [Formula: see text]) produced in most central Au+Au collisions at RHIC-BES energies. The kinetic freeze-out parameters for energies [Formula: see text][Formula: see text] are presented and discussed as a function of collision energy. The [Formula: see text], [Formula: see text], [Formula: see text], [Formula: see text], [Formula: see text], [Formula: see text], [Formula: see text], [Formula: see text], [Formula: see text], and [Formula: see text] BGBW fit results are similar within errors with the kinetic freeze-out parameters of bulk hadrons ([Formula: see text], [Formula: see text], p and [Formula: see text]). The multi-strange kinetic freeze-out parameters indicate that these hadrons tend to decouple earlier from the system than the bulk hadrons, having a smaller average transverse flow velocity.
