A bound on the effective gravitational coupling from semiclassical black holes
R. Brustein, G. Dvali, G. Veneziano
We show that the existence of semiclassical black holes of size as small as a minimal length scale implies a bound on a gravitational analogue of 't-Hooft's coupling $λ_G(…

Causal Propagation of a Charged Spin 3/2 Field in an External Electromagnetic Background
Massimo Porrati, Rakibur Rahman
We present a Lagrangian for a massive, charged spin 3/2 field in a constant external electromagnetic background, which correctly propagates only physical degrees of freedom inside…

Covariant Galileon
C. Deffayet, G. Esposito-Farese, A. Vikman
We consider the recently introduced "galileon" field in a dynamical spacetime. When the galileon is assumed to be minimally coupled to the metric, we underline that both field equa…
