New (g-2)_μ Constraints on Light-Gravitino Models
arXiv:hep-ph/9704439
Abstract
We show that the gravitino contribution to (g-2)_μ is finite in many popular supergravity models, including no-scale supergravity and string and M-theory models. This contribution is greatly enhanced for very light gravitino masses, and leads to new upper bounds on the ratio of the smuon to the gravitino mass.
