The status of cosmological natural selection
Lee Smolin
The problem of making predictions from theories that have landscapes of possible low energy parameters is reviewed. Conditions for such a theory to yield falsifiable predictions fo…
From noncommutative kappa-Minkowski to Minkowski space-time
Laurent Freidel, Jerzy Kowalski-Glikman, Sebastian Nowak
We show that free -Minkowski space field theory is equivalent to a relativistically invariant, non local, free field theory on Minkowski space-time. The field theory we obtain h…
Derivative F-Terms from Heterotic M-Theory Five-brane Instantons
Evgeny I. Buchbinder
We study non-perturbative effects due to a heterotic M-theory five-brane wrapped on Calabi-Yau threefold. We show that such instantons contribute to derivative F-terms described re…
Mach's Holographic Principle
Justin Khoury, Maulik Parikh
Mach's principle is the concept that inertial frames are determined by matter. We propose and implement a precise formulation of Mach's principle in which matter and geometry are i…
Four-Loop Cusp Anomalous Dimension From Obstructions
Freddy Cachazo, Marcus Spradlin, Anastasia Volovich
We introduce a method for extracting the cusp anomalous dimension at L loops from four-gluon amplitudes in N=4 Yang-Mills without evaluating any integrals that depend on the kinema…
Fading Gravity and Self-Inflation
Justin Khoury
We study the cosmology of a toy modified theory of gravity in which gravity shuts off at short distances, as in the fat graviton scenario of Sundrum. In the weak-field limit, the t…
