On Theta Dependence of Glueballs from AdS/CFT
Gregory Gabadadze, Alberto Iglesias
We study the theta dependence of the glueball spectrum in a strongly coupled cousin of large N gluodynamics defined via the AdS/CFT correspondence. By explicitly diagonalizing the…
Lorentz-violating massive gauge and gravitational fields
Gregory Gabadadze, Luca Grisa
We study nonlinear dynamics in models of Lorentz-violating massive gravity. The Boulware-Deser instability restricts severely the class of acceptable theories. We identify a model…
Looking At The Cosmological Constant From Infinite--Volume Bulk
Gregory Gabadadze
I briefly review the arguments why the braneworld models with infinite-volume extra dimensions could solve the cosmological constant problem, evading Weinberg's no-go theorem. Then…
Schwarzschild solution in brane induced gravity
Gregory Gabadadze, Alberto Iglesias
The metric of a Schwarzschild solution in brane induced gravity in five dimensions is studied. We find a nonperturbative solution for which an exact expression on the brane is obta…
Weakly-coupled metastable graviton
Gregory Gabadadze
A graviton of a nonzero mass and decay width propagates five physical polarizations. The question of interactions of these polarizations is crucial for viability of models of massi…
