Light cone actions for gravity and higher spins: some further results

Abstract

It has been suggested that field theories for arbitrary spin can be defined,\nusing the light front formulation of dynamics. The higher order terms\nin the actions are discussed in this paper. We show that the gravity action\ncan be written without ``time''-derivatives in the interaction terms\nin a way which appears generalisable to higher spin. Some problems for\nhigher spins are identified and briefly discussed.
