Scientific paper

We study the scale dependent bias of the halo power spectrum arising from
primordial non-Gaussianity. We present an analytic result of the halo bias
including up to the trispectrum contributions. We find the scale dependent bias
opens a new possibility of probing the relation between the non-linearity
parameters $\fnl$ and $\tnl$.
