  We analyze the current noise, generated at a quantum point contact in
fractional quantum Hall edge state devices, using the chiral Luttinger liquid
model with an impurity and the associated exact field theoretic solution. We
demonstrate that an experimentally relevant regime of parameters exists where
the noise coincides with the partition noise of independent Laughlin
quasiparticles. However, outside of this regime, this independent particle
picture breaks down and the inclusion of interaction effects is essential to
understand the shot noise.
