# Gravity with antisymmetric components

## by Angnis Schmidt-May (Stockholm University)

Europe/Stockholm
Description
The vierbein field of General Relativity contains components which can be shifted by local Lorentz transformations and therefore do not show up in the spacetime metric. In my talk I will show that these components can be made physical in a consistent manner. They then appear in the form of an antisymmetric tensor field which makes the action reminiscent of the bosonic sector of supergravity. Both the metric and the antisymmetric tensor can be made massive by adding a potential term for the vierbein to the Einstein-Hilbert action. The form of this mass potential is inspired by ghost-free massive gravity. I will discuss the features of the resulting theory.
