 Type IIA supergravity

Massless type IIA supergravity is the nonchiral ten-dimensional maximal supergravity with metric, Kalb–Ramond field, dilaton, Ramond-Ramond one-form and three-form potentials, two opposite-chirality Majorana-Weyl gravitini, and two opposite-chirality Majorana-Weyl dilatini. Its massless spectrum has $128$ bosonic and $128$ fermionic polarizations. The two supercharges have opposite ten-dimensional chirality.
