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…
Salvage of Too Slow Gravitinos
Ignatios Antoniadis, Karim Benakli, Wenqi Ke
Gravitinos can inherit a non-relativistic dispersion relation while propagating in a background breaking both supersymmetry and Lorentz symmetry spontaneously. This is because the…
