Action principle for the connection dynamics of scalar-tensor theories    [PDF]

Zhenhua Zhou, Haibiao Guo, Yu Han, Yongge Ma

A first-order action for scalar-tensor theories of gravity is proposed. The Hamiltonian analysis of the action gives a connection dynamical formalism, which is equivalent to the connection dynamics derived from the geometrical dynamics by canonical transformations. Therefore, the action principle underlying loop quantum scalar-tensor theories is recovered.
