Calling the Brane Next Door: The Kaluza-Klein Tower as a Gravitational Information Channel
Karim Benakli
Could two worlds localised on neighbouring branes communicate through gravity alone? We investigate this question in a minimal higher-dimensional framework in which Standard Model…
(Pseudo-)Dirac Gravitinos
Karim Benakli, Arno Goudeau
We discuss low-energy effective theories with a Dirac gravitino. Our main benchmark is Scherk--Schwarz supersymmetry breaking with anti-periodic boundary conditions for fermions on…
Effective Equations of Motion for Massive Higher Spins with Generic Gyromagnetic Ratio
Karim Benakli
We construct consistent effective equations of motion for massive charged particles of spin 2 and spin interacting with constant electromagnetic backgrounds. While tree-level…
Spin-3/2 and spin-2 charged massive states in a constant electromagnetic background
Karim Benakli, Cassiano A. Daniel, Wenqi Ke
We develop in components the superspace action obtained in arXiv:2110.07623 describing the first massive level of the open charged superstring in a flat four-dimensional spacetime.…
Open Superstring First Mass Level Effective Lagrangian: Massive Spin-3/2 Fields in an Electromagnetic Background
Karim Benakli, Cassiano A. Daniel, Wenqi Ke
We derive fully explicit equations of motion, and the associated set of constraints, describing the propagation in a flat space-time of a charged spin-3/2 massive state in a consta…
Open Superstring First Mass Level Effective Lagrangian: Massive Spin-2 in an Electromagnetic Background
Karim Benakli, Cassiano A. Daniel, Wenqi Ke
Minimal coupling leads to problems such as loss of causality if one wants to describe charged particles of spin greater than one propagating in a constant electromagnetic backgroun…
