چکیده
|
We extend a previous self-tuning analysis of the most general scalar-tensor theory of gravity in four dimensions with second order field equations by considering a generalized coupling to the matter sector. through allowing a disformal coupling to matter we are able to extend the fab four model and construct a new class of theories that are able to tune away the cosmological constant on friedmann-lemaitre-robertson-walker backgrounds.
