  Nature of the fractional quantum Hall state at Landau level filling factor
5/2 remains elusive despite intensive experimental and theoretical work. While
the leading theoretical candidates are Moore-Read Pfaffian (Pf) and its
particle-hole conjugate anti-Pfaffian (APf), neither received unambiguous
experimental support. We show that a state that is intermediate between them,
made of alternating stripes of Pf and APf in the bulk, is a viable candidate.
Such a state is shown to be incompressible and thus a charge insulator in the
bulk, but a heat conductor due to the presence of gapless neutral bulk modes.
We argue that properties of such a state is consistent with existing numerical
and experimental work, and discuss possible experimental probes of its
presence.
