  In this paper we present a novel formulation of chaotic hybrid inflation in
supergravity. The model includes a waterfall field which spontaneously breaks a
gauged $U_1(B-L)$ at a GUT scale. This allows for the possibility of future
model building which includes the standard formulation of baryogenesis via
leptogenesis with the waterfall field decaying into right-handed neutrinos. We
have not considered the following issues in this short paper, i.e.
supersymmetry breaking, dark matter or the gravitino or moduli problems. Our
focus is on showing the compatibility of the present model with Planck, WMAP
and Bicep2 data.
