# Effective Lagrangians for physical degrees of freedom in the Randall–Sundrum model

@article{Boos2002EffectiveLF, title={Effective Lagrangians for physical degrees of freedom in the Randall–Sundrum model}, author={Edward E. Boos and Yu. A. Kubyshin and Mikhail N. Smolyakov and Igor P. Volobuev}, journal={Classical and Quantum Gravity}, year={2002}, volume={19}, pages={4591-4605} }

We derive the second variation Lagrangian of the Randall–Sundrum model with two branes, study its gauge invariance and diagonalize it in the unitary gauge. We also show that the effective four-dimensional theory looks different on different branes and calculate the observable mass spectra and the couplings of the physical degrees of freedom of five-dimensional gravity to matter.
