# Proton Decay, Black Holes, and Large Extra Dimensions

@article{Adams2001ProtonDB, title={Proton Decay, Black Holes, and Large Extra Dimensions}, author={F. Adams and G. Kane and M. Mbonye and M. Perry}, journal={International Journal of Modern Physics A}, year={2001}, volume={16}, pages={2399-2410} }

We consider proton decay in theories that contain large extra dimensions. If virtual black hole states are allowed by the theory, as is generally the case, then proton decay can proceed via virtual black holes. The experimental limits on the proton lifetime place strong constraints on the quantum gravity scale Mqg (the effective Planck mass). For most theories, this implies a lower bound of Mqg>1016 GeV. The corresponding bound on the size of large extra dimensions is l<106/n×10-30 cm, where n… Expand
