TITLE: "The Hamiltonian formulation of gravity with explicit Lorentz violation"

SPEAKER:  Prof. CARLOS MARAT REYES  (Universidad del BioBio - Chile)

Abstract: In this talk, we focus on the explicit violation of diffeomorphism in gravity. For this, we start to briefly review the ADM formulation of gravity, a constrained fist-class system. We introduce the scalar and two-tensor sectors of the minimal standard model extension. We show that the constrained structure is modified mildly under certain conditions, and under this approach, the projected equations of motion match the Hamiltonian and momentum constraints. On top of this formulation, we comment on some possible issues that in general may appear and also motivate further phenomenological searches.
