Recent studies on quantum turbulence have shown that the velocity statistics
of a tracer particle obey power law statistics ( Paoletti et al. [ Phys. Rev. Lett.
101 154501 2008], White et al. [Phys. Rev. Lett. 104, 075301 2010 ]) rather than
Gaussian statistics as observed in classical turbulence ( Vincent et al. [ J. Fluid
Mech. 225 1 1991 ] , Noullez [J. Fluid Mech. 339 287 1997]. A superstatistical
model Beck [Phys. Rev.Lett. 98, 064502 2007] is constructed for a Lagrangian
tracer particle in a quantum turbulent flow. The result is in excellent agreement
with a recent experiment done by Paoletti et al. [Phys. Rev. Lett. 101 154501
2008] to observe the motion of tracer particles in quantum turbulent flow of
superfluid 4He.
