摘要

摘要

En 中文
We propose four simple Lagrangians for gravity models with dynamical torsion which are free from ghosts and tachyons. The torsion propagates two massive or massless particles of spin 1(+/-) and 0(+/-) besides the massless graviton 2(+) propagated by metric.
Keyword:
dynamical torsion
alternative gravity
ghost free Lagrangian
