Description
We consider the implications for spatially inhomogenous phases,
and an associated Lifshitz point, in the phase diagram
of QCD. This could produce two critical endpoints in the plane
of T and $\mu$: a Lifshitz point at a higher $T$ and a smaller $\mu$ than for the "usual" critical endpoint (where the quartic scalar coupling vanishes).
The most dramatic signature of a spatially modulated phase is elementary,
with particle production peaked at some characteristic value of the spatial momentum. Such
a signal is suggestive of recent STAR data in the recent Beam
Energy Scan.
