Massive N= 2a supergravity in ten dimensions
LJ Romans - Physics Letters B, 1986 - Elsevier
A new version of the non-chiral N= 2a supergravity in ten dimensions is obtained, in which
the two-index tensor field of the theory “eats” the single vector field and acquires a mass in a …

E11 and M theory
P West - Classical and Quantum Gravity, 2001 - iopscience.iop.org
We argue that 11-dimensional supergravity can be described by a nonlinear realization
