Gauging Higher Derivatives
arXiv:hep-th/9502158 · doi:10.1143/ptp/94.1.105
Abstract
The usual prescription for constructing gauge-invariant Lagrangian is generalized to the case where a Lagrangian contains second derivatives of fields as well as first derivatives. Symmetric tensor fields in addition to the usual vector fields are introduced as gauge fields. Covariant derivatives and gauge-field strengths are determined.
