We study the impact of primordial non-Gaussianity generated during inflation
on the bias of halos using excursion set theory. We recapture the familiar
result that the bias scales as k−2 on large scales for local type
non-Gaussianity but explicitly identify the approximations that go into this
conclusion and the corrections to it. We solve the more complicated problem of
non-spherical halos, for which the collapse threshold is scale dependent.Comment: 13 pages, 3 figures. v2 references added. Matches published versio
