The Lyman-alpha Forest as a tool for disentangling non-Gaussianities
  Detection of primordial non-Gaussianity will give us an unprecedented detail
of the physics of inflation. As observational probes are now exploring new
expanses of the inflationary landscape, it is crucial to distinguish and
disentangle effects of various non-Gaussianities beyond f_NL. In this work, we
calculate the effects of non-Gaussianities parametrized by f_NL and the
cubic-order g_NL, on the Lyman-alpha-forest flux measurements. We give the
expressions of the bias due to f_NL and g_NL, which can be deduced from
accurate measurements of the transmitted flux. We show how these two effects
can be cleanly disentangled via a flux transformation, which also keeps the
error in check.
