A Non-Renormalization Theorem for Local Functionals in Ghost-Free Vector Field Theories Coupled to Dynamical Geometry
Lavinia Heisenberg, Shayan Hemmatyar, Nadine Nussbaumer
We establish a non-renormalization theorem for a class of ghost-free local functionals describing massive vector field theories coupled to dynamical geometry. Under the assumptions…

Inflation, black holes with primary hair, and regular planar black holes from an infinite tower of regularized Lovelock-Proca corrections
Pedro G. S. Fernandes, Jingqian Gou, Lavinia Heisenberg +1
Infinite towers of higher-order corrections to General Relativity have been proposed as a mechanism to resolve singularities in early-universe cosmology and black holes, in a varie…

To bounce or not to bounce in generalized Proca theory and beyond
Lara Bohnenblust, Serena Giardino, Lavinia Heisenberg +1
It is notoriously difficult to construct a stable non-singular bouncing cosmology that avoids all possible instabilities throughout the entire evolution of the universe. In this wo…
