Is there a book or article that discusses the scalar/tensor/scalar-tensor (maybe others as well) theories ? (Look at this [wiki page][1] for a general overview of the theories that I am talking about) So, I am looking for a book that discusses these theories either in general or in detail. It does not have to include all of these theories, it could include some of them as well, but I am mostly interested in scalar/tensor/scalar-tensor ones. Thanks.
