平坦空间和AdS空间中任意自旋场的推广哈密顿量action

Extended hamiltonian action for arbitrary spin fields in flat and AdS spaces

R. R. Metsaev

摘要:

研究了平坦空间和AdS空间中的全对称任意自旋无质量自由场和有质量自由场以及平坦空间中的共形场。得到了这类场的广义规范不变哈密顿作用量。该作用量由相空间场和拉格朗日乘子构成,不受代数约束。导出了相空间场的规范变换和拉格朗日乘子。使用Poincare参数化的AdS空间允许我们对待领域在平坦空间和AdS空间在平等的基础上。

英文摘要:

Totally symmetric arbitrary spin massless and massive free fields in flat and AdS spaces and conformal fields in flat space are studied. Extended gauge invariant hamiltonian action for such fields is obtained. The action is constructed out of phase space fields and Lagrange multipliers which are free of algebraic constraints. Gauge transformations of the phase space fields and Lagrange multipliers are derived. Use of the Poincare parametrization of AdS space allows us to treat fields in flat space and AdS space on equal footing.
