# Effective field theory, black holes, and the cosmological constant

@article{Cohen1999EffectiveFT, title={Effective field theory, black holes, and the cosmological constant}, author={Andrew Glen Cohen and David B. Kaplan and Ann E. Nelson}, journal={Physical Review Letters}, year={1999}, volume={82}, pages={4971-4974} }

Bekenstein has proposed the bound S{le}{pi}M{sup 2}{sub P}L{sup 2} on the total entropy S in a volume L{sup 3} . This nonextensive scaling suggests that quantum field theory breaks down in large volume. To reconcile this breakdown with the success of local quantum field theory in describing observed particle phenomenology, we propose a relationship between UV and IR cutoffs such that an effective field theory should be a good description of nature. We discuss implications for the cosmological…

### M theory as a holographic field theory

We suggest that M theory could be nonperturbatively equivalent to a local quantum field theory. More precisely, we present a “renormalizable” gauge theory in eleven dimensions, and show that it…

Evidence is presented that degrees of freedom inside a black hole should not be viewed as independent from those outside the event horizon, and commutators of spacelike separated operators corresponding to ordinary low-energy observers in Minkowski space are strongly suppressed in string theory.
