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>.
