Minimally modified gravity fitting Planck data better than $$\Lambda $$ Λ CDM
Abstract We study the phenomenology of a class of minimally modified gravity theories called $$f(\mathcal {H})$$ f(H) theories, in which the usual general relativistic Hamiltonian constraint is replaced by a free function of it. After reviewing the construction of the theory and a consistent matter...
