Query: Anomalous tag diffusion in the asymmetric exclusion model with particles
  of arbitrary sizes   Anomalous behavior of correlation functions of tagged particles are studied
in generalizations of the one dimensional asymmetric exclusion problem. In
these generalized models the range of the hard-core interactions are changed
and the restriction of relative ordering of the particles is partially brocken.
The models probing these effects are those of biased diffusion of particles
having size S=0,1,2,..., or an effective negative "size" S=-1,-2,..., in units
of lattice space. Our numerical simulations show that irrespective of the range
of the hard-core potential, as long some relative ordering of particles are
kept, we find suitable sliding-tag correlation functions whose fluctuations
growth with time anomalously slow ($t^{{1/3}}$), when compared with the normal
diffusive behavior ($t^{{1/2}}$). These results indicate that the critical
behavior of these stochastic models are in the Kardar-Parisi-Zhang (KPZ)
universality class. Moreover a previous Bethe-ansatz calculation of the
dynamical critical exponent $z$, for size $S \geq 0$ particles is extended to
the case $S<0$ and the KPZ result $z=3/2$ is predicted for all values of $S \in
{Z}$.
