In quantum field theory the term gravitino refers to the superpartner of the graviton, a Rarita-Schwinger field of spin that appears in supergravity.
In supergravity a field configuration is a connection locally given by a Lie algebra-valued form
on spacetime with values in the super Poincare Lie algebra. Its components in the spin group representation is the gravitino field.
The name derives from the fact that the other two components are identified in gravity with the graviton field.
