Patrick Jefferson Harvard University Negative Branes, Supergroups and Spacetime Signature
[email protected] Negative branes, extended objects with negative charge and tension, were initially introduced as a means to realize supergroup gauge theories in string theory. It was recently proposed that the inclusion of these objects in string theory can dynamically change the signature of spacetime. I will introduce negative branes and briefly discuss their connection to all possible spacetime signatures consistent with supersymmetry.
